Single-particle excitations in the level structure of Cu64

Excited states of the Cu-64 (Z = 29, N = 35) nucleus have been probed using heavy-ion-induced fusion evaporation reaction and an array of Compton-suppressed Clovers as detection system for the emitted. rays. More than 50 new transitions have been identified and the level scheme of the nucleus has been established up to an excitation energy E-x similar to 6 MeV and spin similar to 10 (h) over bar. The experimental results have been compared with those from large-basis shell-model calculations that facilitated an understanding of the single-particle configurations underlying the level structure of the nucleus.
