Oxygen-28 Unbound

Isotopes — atoms of a particular element that have different numbers of neutrons — can be used for a variety of tasks, from tracking climate change to conducting medical research. Investigating rare isotopes, which have extreme neutron-to-proton imbalances and are often created in accelerator facilities, provides scientists with opportunities to…

The Magic is Gone for Certain Atomic Nuclei

Using the power of the Summit supercomputer, researchers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville, have verified the results of a groundbreaking experiment to precisely measure the charge radii of neutron-rich potassium isotopes. The findings challenge current nuclear theory…
