Abstract
The study of the gamma radiation following the inelastic scattering of alpha particles in thin fluorine and lithium targets has led to the discovery of new levels in the compound nuclei and . The () and () reactions in have led to the establishment of the 1.28-Mev level as first-excited state of , and the discovery of the first-excited state (, ) of , respectively. Coulomb excitation is believed to be responsible for the low-energy part of the excitation function of the 196-kev second-excited state in , whereas this effects is much weaker for the 113-kev first-excited state of . No capture gamma rays exist above the known resonance at 0.958 Mev in the reaction .
