Consider a sample of a pure beta-active material

A

All the beta particles emitted have the same energy.

B

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

C

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

D

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