Abstract：
In the framework of the constituent quark model, the spin-orbit splitting of the lowest L=1 excited states of N and Λ are analyzed by using various quark potential models. The results show that only when a two gluon exchange phenomenological flavor dependent l·s term is considered in the potential, the spin-orbit splitting of N and two sets of Λ L=1 states can be explained simultaneously.
