Abstract
The ${K}^{+}$-N interaction is calculated with a quark potential model using the resonating-group method (RGM). For the central interaction, 2\ensuremath{\Elzxh}\ensuremath{\omega} mixed-symmetry harmonic-oscillator components of the nucleon wave function and 2\ensuremath{\Elzxh}\ensuremath{\omega} components of the kaon wave function are included in the calculation of the RGM kernels. These components make a significant contribution to the interaction kernels. The total isospin I=0 S-wave phase shifts are in good agreement with the experimentally determined phase shifts. The I=1 interaction does not exhibit enough repulsion.
