The separation of doublet levels in the mass 5, 6, 14, 15, and 17 systems is calculated from recent semiphenomenological potentials. Shell-model harmonic-oscillator functions are used to represent the nucleons. These wave functions are modified by means of correlation functions which vanish whenever any two nucleons approach closer than the hard-core radius and approach the unmodified oscillator function for large nucleon separations. It is found that the two-body spin-orbit potentials give 50 to 70% of the experimentally observed splittings.

We reexamine the spin-orbit splitting of [Formula: see text] excited states in terms of the SU6 quark-model baryon-baryon interaction. The previous folding procedure to generate the Λα spin-orbit potential from the quark-model ΛN LS resonating-group kernel predicted three to five times larger values for ΔEℓs = Ex(3/2+) - Ex(5/2+) in the model FSS and fss2. This time, we calculate Λα LS Born kernel, starting from the LS components of the nuclear-matter G-matrix for the Λ hyperon. This framework makes it possible to take full account of an important P-wave ΛN-ΣN coupling through the antisymmetric LS(-) force involved in the Fermi-Breit interaction. We find that the experimental value, [Formula: see text], is reproduced by the quark-model G-matrix LS interaction with a Fermi-momentum around kF = 1.0 fm -1, when the model FSS is used in the energy-independent renormalized RGM formalism. On the other hand, the model fss2 gives too large splitting of almost 200 keV, owing to the uncanceled contribution of the scalar-meson exchange LS components.
