Abstract
Abstract The I = 1 and 0 kaon-nucleon s-wave phase shifts have been calculated in a quark potential model using the resonating group method (RGM). The Hill-Wheeler equation has been solved numerically without any parametrization of the KN relative wave-function. The kaon and the nucleon wave-functions have been expanded as sums of several well-chosen gaussian functions, and the sensitivity of the results to the number of terms was analyzed carefully. The I = 0 phase shifts are in agreement with the experimental data. In the I = 1 channel too much repulsion is obtained, probably due to the lack of medium-range boson exchange type attraction.
