N2 - 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 'teff(ρ)ρ' potential and new results are derived for total cross sections. The imaginary part of the teff amplitude is found to increase linearly with the average nuclear density in excess of a threshold value of 0.088±0.004 fm-3. 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 6Li and C.
