Abstract：
The K ⁺N two-body potential is calculated in the framework of the constituent quark model.The derived potential includes the central and spin-orbit contributions with a simple analytic form.The K ⁺N scattering phase shifts are calculated and compared with experimental data.The results show that the potential can provide reasonable good explanation for the K ⁺N data,particularly for the large phase shift of P-wave I=0,J=1/2channel.
