Electron Capture by Beryllium-7
7Be + e− → 7Li + νe
ภาพรวม
Beryllium-7 captures an inner orbital electron, converting a proton to a neutron and producing lithium-7 and a neutrino. This electron capture process occurs with a half-life of 53.2 days. Be-7 is produced in the atmosphere by cosmic ray spallation and is used as an environmental tracer.
