Abstract: Using a shell model diagonalization which includes 2 hbar omega excitations the spin-orbit splittings for mass numbers 5, 15 and 17 are studied. The contributions of the two-body spin-orbit and tensor interactions are studied separately and in combination. It is found that the second-order effects involving the two-body spin-orbit interaction are more important than the second-order tensor effects. For A=5, the overall effect of the higher-shell admixtures is to decrease the p(1/2)-p(3/2) splitting, but for A=15 this splitting is increased by a fair amount, and for A=17 there is only a miniscule increase in the $d(3/2) - d(5/2) splitting. These results are in qualitative agreement with data as well as perturbative analysis.
