Description
A decay spectroscopy experiment was conducted at the NSCL to measure low energy excited states in 71−75Ni populated via the beta-decay of 71−75Co isotopes.
Results from the data analysis of this experiment have revealed a possible beta-decaying isomer in 71Ni which was previously observed in 69Ni. Level schemes
for 71,73Ni have been constructed with reference to shell model (SM) calculations using the NR78 residual interaction. These level schemes show increasing energy of the 5/2− level (attributed to vf5/2 single particle state) with increase in neutron number. This appears to agree with theoretical predictions. We have also reinvestigated the decay of 72Co, where improved data has revealed the presence of a new state tentatively interpreted as a 4+ seniority v=2 member of the ground state band. This observation is a significant step forward in understanding the disappearance of 8+ microsecond-isomers in 72Ni and 74Ni and is also in agreement with the SM calculations using the NR78 interaction.
