Angular distributions for the elastic and inelastic scattering of 0.8 GeV protons from C12, C13, and Pb208 have been measured. Reported are data for the ground, 4.4 MeV 2+, 7.6 MeV 0+, 9.6 MeV 3-, and 14.1 MeV 4+ states of C12; the ground, 3.1 MeV 12+, 3.7 MeV 32-, 6.9 MeV 52+, 7.6 MeV 52-, and 11.9 MeV (?) states of C13; and the ground, 2.6 MeV 3-, and 3.2 MeV 5- states of Pb208. Analyses of the elastic angular distributions are made using the partial wave formalism and the Kerman-McManus-Thaler approach to the nucleon-nucleus optical potential; a realistic spin-orbit term is included. The inelastic transitions are analyzed within the framework of the distorted-wave Born-approximation, using transition strengths consistent with previous low-energy studies of inelastic scattering. A simple single-particle-plus-excited-core model is used for C13. In terms of this analysis, an assignment of Jπ=(52, 72)+ is made for the 11.9 MeV state in C13.
