✦ Synopsis

The large Van de Graaff generator has been engaged in the study of reactions induced in the nuclei of light elements by protons of energies in the range 1.5 to 5 Mev. The yield of gamma rays from the reaction Li 7 q-p--* Be q-y-rays has been measured over this range. By means of a scintillation counter and pulse height analyzer, it has been possible to select for measurement the well-known 14.8 and 17.6 Mev 7-rays. It is found that the yield of these ~,-rays shows a broad peak at 2.1 Mev, the presence of which has previously been in question. Preparations are being made to measure the angular distribution of these ~r-rays in the neighborhood of the resonance.
