Abstract
Observations are reported from the first systematic studies of proton radiative capture at intermediate energies. In addition to captures to the ground and first few excited states, the reactions (,) and (,) reveal unexpectedly strong transitions to isolated high-lying states. These latter transitions could take place via "second-harmonic" giant resonances. Protons on produce a rich spectrum of rays which may arise from captures to high-lying single-particle states.
