Abstract: The low-lying yrast states in the
51
Ca and
52
Sc 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
νp
1
/
2
and
νf
5
/
2
orbitals in the
Ca isotopes appears to be overestimated by the GXPF1A Hamiltonian.
