Abstract

Photon emission in proton-induced reactions at 50 MeV with 115In was studied. Analyses of the measured photon spectrum show that the GDR couples to the compound states as well as to pre-equilibrium states. The centroid and width of the GDR strength function were determined as EGDR = 15.4 ± 0.7 MeV and ΓGDR = 6.2 ± 0.5 MeV. From the measured γ-ray yield above Eγ = 30 MeV, a value of (7.1±1.4) × 10−5 for the hard-photon emission probability per single proton-neutron collision is inferred.
