When the loss of mass in a nuclear reaction is greater than zero but less than 2 m e c 2 the process cannot occur by positron emission, but occurs spontaneously for electron capture.

WebThe positron or antielectron is the antiparticle or the antimatter counterpart of the electron.It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron.When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the production of two or more photons.
