Abstract
Delayed-proton emission following the beta decay of , , and has been investigated in more detail. The number of proton peaks was observed to be six, ten, and seventeen, respectively. The half-lives were determined to be 178±5, 177±5, and 88±1 msec, respectively. Decay schemes are presented by assigning the peaks to virtual levels in , , and . The excitation energies of the first levels were measured to be 5.556±0.020, 5.021±0.020, and 5.90±0.03 MeV, respectively.
