Abstract
Systematic studies on proton angular distribution and proton--radiation angular correlations have been carried out on the reaction throughout the energy range MeV. (.) Both direct and compound-system reaction amplitudes are present; however, the latter appear to dominate. Striking resonant phenomena are observed, and it is suggested that these correspond to quasigiant resonances in the excitation-energy range from 17 to 23 MeV in having a particularly simple structure involving singleproton orbitals coupled to excited core configurations. A systematic correlation has been observed between the population of magnetic substates of the 7.03-MeV state in the residual nucleus and the appearance of backward peaking in the corresponding proton angular distributions. A crude argument relating these phenomena to the participation of a heavy-particle direct stripping mechanism is suggested.
