Abstract: (Elsevier)

Unpolarized and polarized proton radiative capture in 142 Ce is investigated in the frame of the direct-semidirect model in the energy region above the E1 giant resonance. Effects related to the presence of the isovector E2 giant resonance are discussed by a detailed analysis of the E1-E2 interference process and γ-ray angular distribution asymmetries. In spite of the large, screening, direct E2 component, the results suggest recognizable effects due to the collective E2 excitation, provided a polarized proton beam is used.
