Question

The figure shows the decay scheme for $^{12}B$ which undergoes beta decay to either of two levels of $^{12}C$ directly to the ground state or to an excited state.
(i) What is the sequence of events in which gamma decay occurs?
(ii) What is the energy of the emitted electron during betaminus decay, to an excited state?

Answer 1
