In atoms, protons and neutrons orbit the nucleus in one or more shells. Each shell has a specific limit on the number of protons or neutrons it can hold. When these shells are full, the resulting ...

An international team led by scientists from IPN Orsay (CNRS/Université Paris-Sud), CEA, and RIKEN (Japan) has performed the first spectroscopy of the extremely neutron-rich isotopes krypton 98 and ...

Many heavy elements were produced in a spectacular event: the collision of neutron stars. Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our ...

There are two coexisting, competing quantum shapes at low energy in 98Kr, never before seen for neutron-rich Kr isotopes, report scientists. The team also showed that these isotopes experience a ...
