Abstract

Self consistency in the analysis of transmission measurements for K⁺ on several nuclei in the momentum range of 500-700 MeV/c is achieved with a "t_eff(rho)rho" potential and new results are derived for total cross sections. The imaginary part of the t_eff amplitude is found to increase linearly with the average nuclear density in excess of a threshold value. This phenomenological density dependence of the K⁺ nucleus optical potential also gives rise to good agreement with recent measurements of differential cross sections for elastic scattering of 715 MeV/c K⁺ by Li⁶ and C.
