The two-body problem (scattering and bound state) was solved exactly by considering an extension of Yamaguchi's non-local separable potential to include a two-body spinorbit force. The parameters of the potential were determined by obtaining their exact relationships with the lowenergy experimental data (scattering length, effective range, deuteron binding energy, quadrupole and magnetic moments, and the D-state probability). It is found that to fit the data, particularly the magnetic moment, the strength of the spin-orbit force must be comparable to that of the tensor force. This potential was applied to the evaluation of the spin-orbit energy splitting in the nuclei Ca/sup 41/ and O/sup 17/. It is found that the tensor force by itself gives the wrong sign of the splitting and that it is overcompensated by a large contribution (of the correct sign) arising from the two-body spin-orbit force.
