The Disintegration ofLi7by Deuterons

The yield function for the disintegration of lithium bombarded by deuterons has been measured with detectors sensitive to neutrons, gamma-rays, and beta-rays. A gamma-ray of 4.9-Mev energy was found in the course of this investigation. Resonances were found at 0.65, 1.02, and 1.35 Mev corresponding to excited states of the intermediate nucleus (${\mathrm{Be}}^9$) at 17.14, 17.43, and 17.69 Mev. The resonance at 1.35 Mev was found only for the formation of radioactive ${\mathrm{Li}}^8$ accompanied by the emission of a proton. Apparently proton emission is permitted and neutron emission forbidden from the 17.69-Mev state.
