Comprehensive Gamma-Ray Spectroscopy of 62Zn and Studies of Nilsson Parameters in the Mass A = 60 Region

Research output: ThesisDoctoral Thesis (monograph)

Abstract

Comprehensive experimental knowledge of the 62Zn nucleus has been obtained from the combined statistics of four different experiments. The Gammasphere Ge-detector array in conjunction with the 4pi charged-particle detector array Microball was used to detect the gamma-rays in coincidence with evaporated light charged particles. In total twenty seven band structures have been observed in 62Zn, twenty for the first time. The resulting extensive decay scheme comprises almost 260 excited states, which are connected with more than 450 gamma-ray transitions. The multipolarities have been determined for the gamma-ray transitions and as a result spin-parity assignments are given for nearly all energy levels. The collective structures are compared with results from configuration dependent Cranked Nilsson-Strutinsky calculations.
The effective alignment method has been applied to check out the spin, parity and theoretical configuration assignments of the existing experimental bands and thereby identify the behaviour of the band structures in the A ~ 60 mass region.
