When does electron capture emit gamma rays?
No gamma rays are emitted in electron catpure.
Electron capture (EC) is a process that competes with positron (
EC leaves a vacancy in the shell from which the electron was captured. This can be filled with electrons dropping down from a higher-level. This releases energy in the form of a photon classified as
Note that although gamma rays and X-rays are both photons, they are not the same. Gamma rays originate from processes in the nucleus en X-rays originate from the surrounding electron shells.
