Abstract

Protons scattered inelastically from C12 were detected at laboratory angles between 6° and 13° in coincidence with γ rays from deexcitation of the 1+ T=1 state in the recoil nucleus. Coincident cross sections for γ rays emitted normal to the reaction plane and angular correlations for γ rays emitted in the proton scattering plane at angles between 90° and 270° are presented and compared with predictions from both nonrelativistic and relativistic models of proton-nucleus scattering calculated in the impulse approximation. These data display a clear preference for the relativistic-model prediction.
