Physicists have found a new “island of inversion” in the nucleus of molybdenum-84, a perfectly balanced atom with equal numbers of protons and neutrons. The discovery upends a decades-old assumption ...

A new experiment using rare-isotope beams has provided new insight into the origin of proton-rich isotopes known as p-nuclei.

PORTLAND, Ore. — You might have thought that scientists had already cataloged the 118 natural elements–from hydrogen to silicon to uranium–and their various isotopes. Unfortunately, only the first ...

Sixty years ago, the very first samples of rainwater were collected for the Global Network of Isotopes in Precipitation (GNIP), while the science of isotope hydrology was still taking its first steps.

ORNL’s electromagnetic isotope separator, or EMIS, made history in 2018 when it produced 500 milligrams of the rare isotope ruthenium-96, unavailable anywhere else in the world. And EMIS technology ...
