Abstract The quark-delocalization colour-screening model is employed to calculate the effective potential between nucleon and kaon. The results show that the potentials are attractive in the I=0 channel and repulsive in the I=1 channel. The interactions are very weak between K+n or K0p due to the cancellation between I=0 and I=1. It is possible to have a high s-wave resonance (1615MeV), but the width may be too wide to be observed in the experiments.
