Abstract

New isomeric states in the neutron-rich nuclei near the Z=28 and N=40 shell closures have been identified among the reaction products of a 60.3A MeV ⁸⁶Kr beam on a ^natNi target. From the measured isomeric decay properties information about the excited states and their nuclear structure has been obtained. The isomerism is related mostly to the occupation of the neutron g_9/2 orbital, an intruder level in the N=3 fp shell. It is illustrated with the decay properties of ⁶⁹Ni^m, ⁷⁰Ni^m, and ⁷¹Cu^m interpreted within the nuclear shell model.
