Elastic scattering of 500 MeV polarized protons on 4048Ca, 90Zr, and 208Pb and the breakdown of the impulse approximation at small momentum transfers
Description
New 500 Mev anti p + 4048Ca, 90Zr and 208Pb elastic d sigma/dΩ and A/sub y/(theta) data are presented. The small momentum transfer data are not reproduced by the optical model using the second-order Kerman-McManus-Thaler potential based on nucleon-nucleon amplitudes obtained from phase-shift analysis. The systematics of these results, taken together with previous 800 MeV results, suggest that medium modifications to the NN t-matrix are required to obtain an accurate, quantitative description of the 500 to 800 MeV proton-nucleus elastic data in general
