Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

An international collaboration including scientists at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) solved a 50-year-old puzzle that explains why beta decays of atomic ...

Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements at the Accelerator Laboratory of the University of Jyväskylä, Finland, have ...
