Abstract
The proton capture cross sections to the ground and excited states of have been measured at several angles in the proton energy interval between 18 and 40 MeV. The ground state angular distribution, which shows a significant interference effect above 40 MeV, results in reasonable agreement with semidirect capture calculations. Transitions to final bound and unbound 1p-1h states in having a dominant hole have also been measured. Resonances built on these residual states have been systematically observed above MeV; the possible interpretation of these states as giant dipole resonances built on excited states is discussed.
