Yrast structure of the neutron-rich N=31 isotones {sup 51}Ca and {sup 52}Sc.
The low-lying yrast states in the {sup 51}Ca and {sup 52}Sc nuclei were investigated to obtain information on the evolution of the p1/2 and f5/2 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}p1/2 and {nu}f5/2 orbitals in the Ca isotopes appears to be overestimated by the GXPF1A Hamiltonian.
