EFFECTIVE SPIN-ORBIT POTENTIAL IN CORRELATED HEAVY NUCLEI
A many-body system is considered in which a particle N moves under the influence of the remaining N-1 particles, taken te be nucleons, and every total paricle-particle interaction contains a repulsive core. An expression is derived for that part of the effective one-body potential felt by particle N which is caused by a specific portion v/sub 1N/ of its interaction with each of the nucleons i = 1, N-1, on the basis of a system wave function of the Jastrow type, neglecting exchange contributions involving paricle N. This result is used to estimate the spin-orbit splittings in the region of Pb/sup 208/ generated by the Gammel-Thaler and Signell-Zinn-Marshak two-body spin-orbit potentials. In both cases the theoretical splittings are of the correct sign and about the right magnitude to explain the observed doublet separations. (auth)
