摘要：

The low-lying levels in Cr-59 have been studied with the C-13(Ca-48,2p) reaction at a beam energy of 130 MeV. Data on Mn-59, produced via the pn-evaporation channel, have set limits on the spin of the ground state in Cr-59 and enabled some spin-parity assignments of excited states to be made. The structure obtained in this study is clearly inconsistent with results of shell-model calculations within the full fp shell and requires inclusion of the nug(9/2) orbital. The sequence of states is understood within Nilsson model calculations assuming a moderate oblate ground-state deformation.
