    Abstract

    High-angular-momentum states in 64Zn were populated in the 40Ca( 28Si,4p) reaction at a beam energy of 122 MeV. Evaporated, light, charged particles were identified by the Microball, while γ rays were detected using the Gammasphere array. The main focus of this paper is on two strongly coupled, collective bands. The yrast band, which was previously known, has been linked to lower-lying states establishing the excitation energies and angular momenta of in-band states for the first time. The newly identified excited band decays to the yrast band but firm angular-momentum assignments could not be made. In order to interpret these structures cranked-Nilsson-Strutinsky calculations have been performed. The calculations have been extended to account for the distribution of nucleons within a configuration. The yrast collective band is interpreted as based on the π(f 7/2) -1(p 3/2f 5/2) 2(g 9/2) 1 ν(p 3/2f 5/2) 4(g 9/2) 2 configuration. There are several possible interpretations of the second band but it is difficult to distinguish between the different possibilities.
