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 ...

Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, ...

Although the periodic table is filled with elements, nuclear fusion at the center of stars can only produce elements with atomic masses lower than iron—after than, neutron captures processes known as ...

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 ...

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for ...

In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in ...
