The spin-orbit splitting of the p1/2 and p3/2 hole states in N15 is studied with realistic nuclear forces and the variational cluster Monte Carlo method. The results show that the two-nucleon LS forces give approximately half of the observed splitting, while the other half comes from pion exchange interactions between three or more nucleons. The observed splitting is fairly well reproduced by these calculations based on nonrelativistic nuclear many-body theory.
