Scientists have discovered the first indication of nuclear fission occurring amongst the stars. The discovery supports the idea that when neutron stars smash together, they create "superheavy" elements — heavier than the heaviest elements of the periodic table — which then break down via nuclear fission to birth elements like the gold in your jewelry. Nuclear fission is basically the opposite of nuclear fusion. While nuclear fusion refers to the smashing of lighter elements to create heavier elements, nuclear fission is a process that sees energy released when heavy elements split apart to create lighter elements. Nuclear fission is pretty well known, too. It's actually the basis of energy-generating nuclear power plants here on Earth — however, it had not been seen occurring amongst the stars before now.  "People have thought fission was happening in the cosmos, but to date, no one has been able to prove it," Matthew Mumpower, research co-author and a scientist at Los Alamos National Laboratory, said in a statement.

AI for astrophysics: Algorithms help chart the origins of heavy elements

The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time. Testing this theory and answering other astrophysical questions requires predictions for a vast range of masses of atomic nuclei. Los Alamos National Laboratory scientists are front and center in using machine learning algorithms (an application of artificial intelligence) to successfully model the atomic masses of the entire nuclide chart — the combination of all possible protons and neutrons that defines elements and their isotopes.

“Many thousands of atomic nuclei that have yet to be measured may exist in nature,” said Matthew Mumpower, a theoretical physicist and co-author on several recent papers detailing atomic masses research. “Machine learning algorithms are very powerful, as they can find complex correlations in data, a result that theoretical nuclear physics models struggle to efficiently produce. These correlations can provide information to scientists about ‘missing physics’ and can in turn be used to strengthen modern nuclear models of atomic masses.”

Simulating the rapid neutron-capture process

Most recently, Mumpower and his colleagues, including former Los Alamos summer student Mengke Li and postdoc Trevor Sprouse, authored a paper in Physics Letters B that described simulating an important astrophysical process with a physics-based machine learning mass model. The r process, or rapid neutron-capture process, is the astrophysical process that occurs in extreme environments, like those produced by  neutron star collisions. Heavy elements may result from this “nucleosynthesis”; in fact, half of the heavy isotopes up to bismuth and all of thorium and uranium in the universe may have been created by the r process. 

But modeling the r process requires theoretical predictions of atomic masses currently beyond experimental reach. The team’s physics-informed machine-learning approach trains a model based on random selection from the Atomic Mass Evaluation, a large database of masses. Next the researchers use these predicted masses to simulate the r process. The model allowed the team to simulate r-process nucleosynthesis with machine-learned mass predictions for the first time — a significant feat, as machine learning predictions generally break down when extrapolating. 

“We’ve shown that machine learning atomic masses can open the door to predictions beyond where we have experimental data,” Mumpower said. “The critical piece is that we tell the model to obey the laws of physics. By doing so, we enable physics-based extrapolations. Our results are on par with or outperform contemporary theoretical models and can be immediately updated when new data is available.”

Investigating nuclear structures

The r-process simulations complement the research team’s application of machine learning to related investigations of nuclear structure. In a recent article in Physical Review C selected as an Editor’s Suggestion, the team used machine learning algorithms to reproduce nuclear binding energies with quantified uncertainties; that is, they were able to ascertain the energy needed to separate an atomic nucleus into protons and neutrons, along with an associated error bar for each prediction. The algorithm thus provides information that would otherwise take significant computational time and resources to obtain from current nuclear modeling.

In related work, the team used their machine learning model to combine precision experimental data with theoretical knowledge. These results have motivated some of the first experimental campaigns at the new Facility for Rare Isotope Beams, which seeks to expand the known region of the nuclear chart and uncover the origin of the heavy elements.

From Tennessee Lookout:

MASON, Tenn. – The Tennessee Comptroller issued an unusual appeal last week to residents of this small, majority Black town, which occupies fewer than two square miles in rural west Tennessee.

“In my opinion, it’s time for Mason to relinquish its charter,” Comptroller Jason Mumpower wrote in a letter mailed to each one of Mason’s 1,337 property owners.

Mumpower urged local residents to “encourage your local officials to do what’s necessary to allow Mason to thrive. There is no time to waste.”

State comptrollers, responsible for financial oversight of local government, typically communicate directly with elected local leaders and not their constituents. “We have not issued a letter to citizens like this before,” Comptroller spokesman John Dunn said, noting it is “unprecedented for us to publicly call for a town charter to be relinquished.”

But the Comptroller’s unprecedented public callout comes at an unprecedented time not only for Mason, but for the state. Mason, located in the southeastern corner of Tipton County, now finds itself with some of the most coveted real estate in Tennessee.

It’s one of the nearest towns to the massive new site to be built for Blue Oval City, a key component in Ford Motor Co’s multibillion-dollar pivot to electric vehicle manufacturing.

Mumpower’s letter has infuriated Mason’s part-time elected officials, who insist they have no intention of ceding their town’s 153-year-old charter – which would subsume the largely African-American, majority Democratic community under the governance of Tipton County, which is predominantly white and Republican.

“This is our home. We were born and raised here. The majority of the town is homegrown people that live here,” Vice Mayor Virginia Rivers said. “He is trying to conquer and divide us. It’s akin to a hostile take-over and it’s not hard to figure out why here, why now.”

Town leaders are accusing Mumpower and other state officials of big-footing a long-ignored, largely Black community now that major investment is heading its way.

Mason is 60% Black and includes descendants of men, women and children enslaved in the area before Emancipation. For more than a century the town was led by White elected officials.

That changed in 2016, when fraud and mismanagement allegations led to the resignations of nearly all City Hall officials, all of whom were White. Mason’s current mayor, vice mayor and five of its six alderman are Black.

“It’s because of the Black people that are in office,” said Rivers, who first became Vice Mayor in 2021.

“And it’s because of all the places in the world, Blue Oval could have selected, they selected here. There’s no way Mason won’t prosper and grow. And now they want to take it away from us.”

The Comptroller’s office:

Yet again like in the past. New day, new Jim Crow-esque tactics, perfectly timed takeovers. This Black American town needs to be promptly saved without handing a damn thing over. The town elected mostly Black officials back in 2015. They’ve been trying to pay off the debt from when the town was previously ran by mostly white officials. Literally playing catch-up. 

This ain’t nothing but a glimpse of what it looks like before eventually uprooting and displacing Black people off the land they have resided on since forever and where their ancestors labored said land as property in chattel slavery and the move into Jim Crow.  

There’s a change.org petition to sign and share to get the word out there.

This person suggested to put Ford in the hot seat by sending a letter like this. Others are suggested to call their office. 

This is the CEO of Ford’s twitter.

Something gotta give. 

This shit should be on the news. But as usual, they make it known after the deed is done or not at all and you end up finding out years later.

First hints of nuclear fission in cosmos

The elements above iron on the periodic table are thought to be created in cataclysmic explosions like the merger of two neutron stars or in rare classes of supernovae. New research suggests fission may operate in the cosmos during the creation of the heavy elements. Combing through data on a variety of elements that reside in very old stars, researchers have found a potential signature of fission, indicating that nature is likely to produce superheavy nuclei beyond the heaviest elements on the periodic table.

“People have thought fission was happening in the cosmos, but to date, no one has been able to prove it,” said Matthew Mumpower, a theoretical physicist at Los Alamos National Laboratory and co-author of a paper in Science presenting the research.

Using the latest observations, Mumpower said, the researchers found a correlation between light precision metals like silver and rare earth nuclei like europium. When one of these groups of elements goes up, the corresponding elements in the other group also increase — the correlation is positive.

‘Incredibly profound” evidence of fission

“The only plausible way this can arise among different stars is if there is a consistent process operating during the formation of the heavy elements,” Mumpower said. The team tested all the possibilities and fission was the only explanation that was able to reproduce the trend.

“This is incredibly profound and is the first evidence of fission operating in the cosmos, confirming a theory we proposed several years ago,” Mumpower said. “As we’ve acquired more observations, the cosmos is saying hey, there’s a signature here, and it can only come from fission.”

The research also indicates that elements with an atomic mass (the number of protons plus neutrons) of 260 — heavier than those charted at the high end of the periodic table — may exist.

Mumpower developed the fission models used to predict and guide the observational findings, which were led by study author Ian Roederer of North Carolina State University.

Heavy research

Astrophysicists have long believed heavy elements beyond iron were formed in stellar explosions called supernova or when two neutron stars merged. As the name implies, the latter are composed largely of neutrons, which together with protons form the nuclei of all atoms. Through the rapid-neutron capture process, dubbed the r-process, atomic nuclei grab neutrons to form heavier elements. Whether some grow too heavy to hold together and split, or fission, forming two atoms of lighter but still heavy elements (and releasing tremendous energy) has remained a mystery for a half century. 

In a 2020 paper, Mumpower first predicted the distributions of fission fragments for r-process nuclei. A subsequent study led by collaborator Nicole Vassh at TRIUMF predicted the co-production of light precision metals and rare earth nuclei. This co-production of elements like elements ruthenium, rhodium, palladium and silver, and those like europium, gadolinium, dysprosium and holmium, can be tested by comparing the prediction with elemental abundances in a collection of stars.

The new analysis led by Roederer combed through observational data from 42 stars and found precisely the predicted correlation. The pattern provides a clear signature of fission creating these elements and a similar pattern of elements slightly heavier and higher on the periodic table.

“The correlation is very robust in r-process enhanced stars where we have sufficient data. Every time nature produces an atom of silver, it’s also producing heavier rare earth nuclei in proportion. The composition of these element groups are in lock step,” Mumpower said. “We have shown that only one mechanism can be responsible — fission — and people have been racking brains about this since the 1950s.”

From stockpile stewardship to the stars

“At Los Alamos, we developed nuclear fission models because we can’t measure everything that’s relevant for weapons research as part of the Laboratory’s mission,” Mumpower said. The models allow physicists to interpret experiments and fill in data when measurements are lacking. Since the United States halted testing of nuclear weapons in 1992, experimental data on fission has been limited.

The models perform exceptionally well when compared to measured data and thus give credence to their extrapolations where there are no measurements. The nuclear inputs of both short-lived and long-lived species are required for studies of heavy element formation, Mumpower said. Fission yields are products of the process of splitting relatively heavy atoms into lighter ones — the same process used in nuclear weapons and reactors.

The image shows two neutron stars colliding to releasing neutrons that radioactive nuclei rapidly capture. The combination of neutron capture and radioactive decay produces subsequently heavier elements. The entire process is believed to happen in a single second.
