States in Odd-OddCu62Populated by the Decay ofZn62

The decay of 9.2-h ${}_{}{}^{62}{}_{}{}^{}\mathrm{Zn}$ to states in odd-odd ${}_{}{}^{62}{}_{}{}^{}\mathrm{Cu}$ has been studied with the aid of large-volume Ge(Li) $\gamma$-ray detectors. 19 $\gamma$ rays were found to belong to this decay, and all were placed in a decay scheme containing states in ${}_{}{}^{62}{}_{}{}^{}\mathrm{Cu}$ at 0 ($J^{\pi }=1^{+}$), 40.94 ($2^{+}$), 243.44 ($2^{+}$), 287.98 ($2^{+}$), 426.3 ($3^{+}$), 548.4 ($1^{+}$), 637.5 ($1^{+}$), 915.6 (${\mathrm{}\left[1\right]\mathrm{}}^{+}$), 1142.5 (${\mathrm{}[0,1]\mathrm{}}^{+}$), 1280.8 (${\mathrm{}[0,1]\mathrm{}}^{+}$), and 1429.9 keV (${\mathrm{}[1,0]\mathrm{}}^{+}$). These were combined with existing in-beam $\gamma$-ray particle-transfer data to yield a rather complete ${}_{}{}^{62}{}_{}{}^{}\mathrm{Cu}$ level scheme. The status of shell-model calculations in this nuclear region is discussed, and it is demonstrated that a gratifying number of facts about the low-lying ${}_{}{}^{62}{}_{}{}^{}\mathrm{Cu}$ states can be explained using simple odd-odd configurations as predicted by the neighboring odd-mass nuclei.
