摘要：

The low-lying yrast states in the Ca-51 and Sc-52 nuclei were investigated to obtain information on the evolution of the p(1/2) and f(5/2) neutron single-particle orbitals in neutron-rich nuclei near proton number Z=20. Level structures associated with neutron excitations into these two orbitals and with proton excitations across the Z=20 shell gap were identified. Shell-model calculations with the recently proposed GXPF1A interaction account reasonably well for the fp-shell states. The energy separation between the nu p(1/2) and nu f(5/2) orbitals in the Ca isotopes appears to be overestimated by the GXPF1A Hamiltonian.
