A magnetic-lens type beta-ray spectrometer was used to study the radiations from the reaction N/sup 15/(d,p)N/sup 16/. Targets of CrN/sup 15/ were made by induction-heating chromium foils to 1300 deg C in a N/sup 15/- enriched gas atmosphere. Photoelectron spectra of gamma rays K-converted in Cd and Au radiators yielded gamma -ray energies of 397.3 plus or minus 1.0, 296.2 plus or minus 1.0, 275.9 plus or minus 397.3 plus or minus 1.0, 296.2 plus or minus 1.0, and 120.1 plus or minus 0.5 kev are inferred from the gamma - ray energies. The K internal conversion coefficient of the 120 kev first-excited to ground state transition of N/sup 16/ was measured by the external-internal conversion method to be 7.23(1 plus or minus 0.20) x 10/sup -3/. This value shows the 120 kev transition to be E2, which is consistent with the previously indicated spin and parity assignments of 2/sup -/ and 0/sup -/ for the ground level and first-excited level, respectively. The relative gamma -ray branching of individual levels was also measured. (auth)
