Spins of 5, 6, 3, 4 have been assigned to the levels at 2935, 2490, 2170, and 1540 kev in the Cd/ sup 110/ level scheme. The 1355- and 1510-kev gamma rays are dipole-quadrupole mixtures. (auth) l647l LIGHT-PARTICLE SPECTRA FROM THE NITROGEN Energy spectra and angular distributions were measured for protons and alpha particles resulting from the nitrogen bombardment of oxygen. It was found that the angular distributions of protons are reasonably isotropic whereas alpha particles are peaked in the forward direction. The energy distributions at various angles were compared with the predictions of a simple level density formula w = C expSTA2(aE*)/sup 1/2/!. The constant a was found to be a = 2.5 plus or minus 0.2 from proton spectra, a == 1.3 plus or minus 0.2 from alpha -particle spectra at all angles measured. The energy spectrum of deuterons was measured at 15 deg and a value of a = l.8 plus or minus 0.3 was found. Unexplained structure was observed in the spectrum of alpha particles emitted at zero degrees. After correction for the phase space available and the barrier penetration, it was found that alpha particles are emitted on the order of ten times more copiously than protons, while deuterons are about half as abundant as protons.
