Consider a sample of a pure beta-active material

All the beta particles emitted have the sae energy

The beta particles originally exist inside the nucleus and are ejected at the time of beta decay

The antineutrion emitted in a beta decay has zero mass and hence zero momentum

The active nucleus changes to one of its isobars after the beta decay
