Researchers Move Closer To Switching Nuclear Isomer Decay On And Off

Livermore researchers have moved one step closer to being able to turn on and off the decay of a nuclear isomer. The protons and neutrons in a nucleus can be arranged in many ways. The arrangement with the lowest energy is called the ground state and all ...
