Beta Decay Process

In the beta decay process: a neutron decays into a proton and an electron (beta radiation).
The process also requires the emission of a neutrino (in this case an anti-neutrino) to maintain momentum and energy balance.

This material is considered too complex to be written about at an intermediate or beginner level, so all levels appear in the advanced form.
