10-MEV PROTON REACTION CROSS SECTIONS COMPARED WITH SURFACE AND VOLUME ABSORPTION OPTICAL MODELS OF THE NUCLEUS

The (p,n) cross sections were measured at 9.85 Mev for self-supporting thin targets of Al, Ti, Fe, Co, Ni, Cu/sup 63/, Cu/sup 65/, Rh, Ag, Sn, Ta, and Au. The (p,2n) contributions were calculated using the statistical model of the nucleus for Rh, Ta, Ag, and Au. Charged-particle emission was assumed negligible in Ta and Au because of small Coulomb penetrabilities. Approximate proton reaction cross sections were obtained by adding (p,n) and (p,2n) cross sections to (p,p') and (p, alpha ) cross sections previously reported by Meyer and Hintz. These results were compared with volume absorption and surface absorption optical- model calculations of proton reaction cross sections. The parameters for both model calculations were obtained prior to this work by fitting proton elastic scattering and polarization data. The results indicate a surface-absorption potential rather than a volume-absorption potential. (auth)
