Abstract
New 500-MeV +, , and elastic and data are presented. The small-momentum-transfer data are not reproduced by the second-order Kerman-McManus-Thaler optical potential which uses free nucleon-nucleon amplitudes. The systematics of these results, taken together with previous 800-MeV results, suggest that medium modifications to the matrix are required to obtain an accurate description of the 500-800-MeV proton-nucleus elastic data in general.
