Level Structures of Cu59 and Cu61 Studied by means of the Ni58,60(He3,d) Reactions

Abstract

The reactions ${\mathrm{Ni}}^{58,60}({\mathrm{He}}^3,d){\mathrm{Cu}}^{59,61}$ have been studied at 16.4-MeV incident energy. Forty-two states up to 7.1-MeV excitation were observed in ${\mathrm{Cu}}^{59}$, and 82 states up to 8.5 MeV were observed in ${\mathrm{Cu}}^{61}$. Deuteron angular distributions were recorded in the angular interval 7°-60° and, with the aid of distorted-wave analysis, spectroscopic information has been obtained for those states which are fed by the more intense transitions. The low-lying level structures are compared with the unified-model predictions.
