Abstract

Lifetimes of excited states in the neutron-deficient nucleus Zn-61 were measured employing the recoil-distance Doppler-shift (RDDS) and the electronic fast-timing methods at the University of Cologne. The nucleus of interest was populated as an evaporation residue in Ca-40(Mg-24, n2p)Zn-61 and Ni-58(alpha,n)Zn-61 reactions at 67 and 19 MeV, respectively. Five lifetimes were measured for the first time, including the lifetime of the 5/2(1)(-) isomer at 124 keV. Short lifetimes from the RDDS analysis are corrected for Doppler-shift attenuation (DSA) in the target and stopper foils. Ambiguous observations in previous measurements were resolved. The obtained lifetimes are compared to predictions from different sets of shell-model calculations in the fp, f(5/2)pg(9/2), and multishell fp-g(9/2)d(5/2) model spaces. The band built on the 9/2(1)(+) state exhibits a prolate deformation with beta approximate to 0.24. Especially, the inclusion of cross-shell excitation into the 1d(5/2) orbital is found to be decisive for the description of collectivity in the first excited positive-parity band.
