In positron emission, a proton is converted into a neutron, a positron, and a neutrino:
p --> n + e + v
this conversion occures only in a nucleus, because this process consumes energy (the neutron and positron have a higher mass than the proton).
The energy needed is twice the rest mass energy of the electron: 1.022 MeV.
Why exactly 2*mass(electron).
I would excpect it to be something like
(mass of neutron + mass of electron)-mass of proton.
Thanks in advance
