The gamma-ray excitation fumction of the Ne/sup 22/(p, gamma )Na/sup 23/ reaction for protons of energies in the range 500 to 900 kev has been measured. Narrow resonances at 636, 660, with earlier workers. The 660-kev and 943-kev resonances may be due to contaminants, but the remainder were assigned unambiguously to the above reaction, and their gamma-ray spectra examined. A detailed study, including angular distribution measurements, was made of the resonances at 636 and 854 kev. In all four resonances ground-state radiation was observed, and in the upper three radiation to the first excited state was found. A cascade through the 3.92-Mev level was observed in the 854-kev resonance. The results suggest that the first excited state has spin 5/2, even parity; the 3.92- Mev level, 5/2 or 7/2+; the 9.40-Mev capture state 1/2--; and the 9.61Mev capture state 3/2, + or --. (auth)
