In 80% of all events, 6831 Ga (T1/2 = 68 min) decays to the ground state of 6830Zn (stable), with
emission of a high energy charged particle (Emax = 1.89 MeV). In 20% of all events, 6831 Ga decays
to an excited state of 68 30Zn that lies 1.08 MeV above the ground state, without emission of that
charged particle.
