摘要：

The K+-nucleon effective interaction in nuclear matter is derived using the Brueckner theory from a K+-nucleon potential built partly from the constituent quark model, partly in a phenomenological way. The influence of the conventional medium effects arising from the renormalization of the interaction on the K+-nucleus optical potential and on the elastic differential cross section at 800MeV/c is analyzed. Density-dependent variations of the effective nucleon mass are also introduced. These less-conventional medium effects lead to more important modifications of the K+-nucleus differential cross section and improve significantly the agreement with the experimental data. © 1990.
