电子俘获![]() ![]() 电子俘获(英语:Electron capture)是富质子的原子核吸收一个自身轨道的电子(使一个质子转变为中子)、并同时发射出一个中微子的过程。伴随发生的过程还包括光子的辐射(伽马射线),使新产生原子核的能级降至基态。
英语百科
Electron capture 电子俘获![]() Electron capture (K-electron capture, also K-capture, or L-electron capture, L-capture) is a process in which the proton-rich nucleus of an electrically neutral atom absorbs an inner atomic electron, usually from the K or L electron shell. This process thereby changes a nuclear proton to a neutron and simultaneously causes the emission of an electron neutrino. |
