摘要：
The K+-nucleon two-body potential is derived in the framework of the constituent quark model and it may provide reasonable explanation for the large K+-nucleon scattering phase shift of P-wave I = 0, J = 1/2 channel. On the basis of the derived K+-nucleon interaction, the real part of the K+-nucleus optical potential is constructed. Reasonable good agreement between theoretical cross-section and experimental data may be reached by requiring a weak imaginary part of the optical potential, as expected for the K+-nucleus scattering.
