Cross-section and analyzing-power measurements are presented for inelastic proton excitation of the 5, T =0 state at 9.70 MeV, the 6, T=O state at 11. 58 MeV, and the 6, T=1 state at 14.35MeV in Si for incident proton energies of 80, 100, 134, and 180 MeV. These results are analyzed using the distorted-wave impulse approximation, an energy-dependent optical potential derived from the elastic scattering, and several different free and density-dependent forms for the effective nucleon-nucleon interaction. The energy and momentum-transfer dependence of the cross section and analyzing power is examined in detail. The extraction of nuclear structure information from analyses of inelastic proton scattering is discussed.NUCLEAR REACTIONS 8Si(p, p') 8Si, E"=80, 100, 134, 180 MeV; measured 0 (Ep 8) A {Ep 0) E:9 70 MeV (5 T 0) 1 1 58 MeV (6 T 0) 14 35 MeV (6, T =1).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
