Excitation of Giant Resonances by InelasticHe3Scattering

Abstract
Inelastic He3 scattering at 71 MeV on twelve nuclei ranging from Al27 to Bi209 shows an enhancement of the continuum very similar to that observed in electron and proton scattering. The effect is ascribed to a giant multipole state. The strength of the excitation indicates an E2 character for the state.
