Abstract：
In this paper, we study the N-N and N-Δ spin orbit forces in the quark model. The results are: (1) the N-N spin orbit force is attractive for the triplet odd state, this feature is qualitatively agreement with the phenomenological potential which is determined by the N-N scattering data. (2) the direct term of the Δ-N spin orbit force is attractive mainly and the exchange term of that is attractive for the case of ST=12 and 21, repulsive for the case of ST=11 and 22. All of these results will be helpful to understand the property of the N-Δ spin-orbit force.
