Abstract
Data from three experiments using the heavy-ion fusion evaporation-reaction 36Ar+28Si have been combined to study high-spin states in the residual nucleus 60Ni, which is populated via the evaporation of four protons from the compound nucleus 64Ge. The GAMMASPHERE array was used for all the experiments in conjunction with a 4 charged-particle detector arrays (MICROBALL, LUWUSIA) and neutron detectors (NEUTRON SHELL) to allow for the detection of rays in coincidence with the evaporated particles. An extended 60Ni level scheme is presented, comprising more than 270-ray transitions and 110 excited states. Their spins and parities have been assigned via directional correlations of rays emitted from oriented states. Spherical shell-model calculations in the fp-shell characterize some of the low-spin states, while the experimental results of the rotational bands are analyzed with configuration-dependent cranked Nilsson-Strutinsky calculations.
