Abstract
A local, state-independent nuclear single-particle potential for
was developed by suitably shaping the nuclear central term and
the related spin-orbit term of Thomas type. The aim was to reproduce
accurately the excitation energies of the known single-particle states in
,
,
and
as well as the recently
observed dependence of the spin-orbit splittings on angular momentum
and principal quantum number n. As result, a set of orthogonal
proton and neutron wave functions was obtained which were used for a
consistent reanalysis of proton and neutron single-particle transfer
reactions on
.
The quality of the description of measured
angular distributions is comparable with that obtained originally with
individual ``best fit'' potentials. The resulting single-particle
spectroscopic factors amount on the average to
0.7. Single- particle
densities derived from these wave functions are in qualitative
agreement with measured charge and mass densities for
.
