Outdone only by nuclear fusion, the process of nuclear fission releases enormous amounts of energy. The ‘spicy rocks’ that are at the core of both natural and artificial fission reactors are generally ...

LOS ALAMOS, N.M., Dec. 7, 2023 — 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 ...

Neutron capture cross section measurements at the Japan Proton Accelerator Research Complex (J-PARC) have been pivotal in advancing our understanding of nuclear reactions that underpin both ...

Models for how heavy elements are produced within stars have become more accurate thanks to measurements by RIKEN nuclear physicists of the probabilities that 20 neutron-rich nuclei will shed neutrons ...

On March 9, President Biden laid out his funding priorities in his proposed budget for 2024. Of these funding priorities, he included a record $1 billion in new investments in fusion programs. In a ...

The possible emission rate of particle-stable tetraneutron, a four-neutron system whose existence has been long debated within the scientific community, has now been investigated. Researchers looked ...

Researchers from the University of Washington, Seattle, and Los Alamos National Laboratory used the Summit supercomputer to conduct the first fully microscopic, quantum many-body simulation of a ...

Neutron clustering measurements at the Walthousen Reactor Critical Facility at Rensselaer Polytechnic Institute in Schenectady, NY. (Credit: Los Alamos National Laboratory) The first ever live ...

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the ...

Atomic bombs work via a process called nuclear fission that involves atom splitting. Shortly after scientists discovered nuclear fission, the possibility of a bomb was quickly realized. Albert ...
