Tensor interaction contributions to singleparticle energies
Abstract
We calculate the contribution of the nucleonnucleon tensor interaction to singleparticle energies with finiterange Gmatrix potentials and with zerorange Skyrme potentials. The Skx Skyrme parameters including the zerorange tensor terms with strengths calibrated to the finiterange results are refitted to nuclear properties. The fit allows the zerorange protonneutron tensor interaction as calibrated to the finiterange potential results which gives the observed change in the singleparticle gap {epsilon}(h{sub 11/2}){epsilon}(g{sub 7/2}) going from {sup 114}Sn to {sup 132}Sn. However, the experimental l dependence of the spinorbit splittings in {sup 132}Sn and {sup 208}Pb is not well described when the tensor is added, owing to a change in the radial dependence of the total spinorbit potential. The gap shift and a good fit to the l dependence can be recovered when the likeparticle tensor interaction is opposite in sign to that required for the G matrix.

We analyze the evolution of the spinorbit splittings in the Ca isotopes and in the N=28 isotones. We also focus on the reduction of the spinorbit splittings associated with f and p orbits from {sup 48}Ca to {sup 46}Ar. We conclude that adding the tensor contribution can qualitatively explain in most cases the empirical trends, whereas this is not the case if one simply employs existing Skyrme parametrizations without the tensor force.

Analytic expressions for the single particle energies with a quadrupolequadrupole interaction and the relation to Elliott{close_quote}s SU(3) model
We present an analytical proof and a generalization of the FayacheSharonZamick relation between single particle energy splittings and the SU(3) limit in Elliott{close_quote}s model. {copyright} {ital 1997} {ital The American Physical Society} 
{lambda}hypernuclei singleparticle energies with the Nijmegen ESC04 baryonbaryon interaction
{lambda}hypernuclei singleparticle energies are calculated for the new Nijmegen ESC04 baryonbaryon interaction. A BruecknerHartree approach is employed. Whereas good agreement with experimental results is obtained for the A=3,4, and 5 systems, the heavier systems are considerably overbound. A possible source for some of the overbinding is the spinorbit odd interaction and its effect on the {sup 3}P{sub 2} channel. 
Monopole Interaction and SingleParticle Energies
We derived an expression of singleparticle energies, and it is expressed in terms of monopole strengths and number operators. The monopole component of NN interaction, which is defined as the lowestorder terms of multipole expansion, is well renormalized into the singleparticle energies.
