The Strong Nuclear Force
- The strong nuclear force is repulsive for very small seperations of nucleons (less than 0.5fm).
- As nucleon seperation increases past 0.5fm, the strong nuclear force becomes attractive. It reaches a maximum attractive value and then falls rapidly to zero after 3.0fm.
- The electromagnetic force in the nucleus extends over a much larger range (infinitely).

- Is the emission of an electron and an anti-neutrino.
- This happens in isotopes that are neutron rich.
- When a beta particle is emitted, one of it neutrons is changed into a proton.
- The proton number increases by one, and the nucleon number stays the same.
- The anti-neutrino emitted carries away some energy and momentum.
