Abstract
The energies of twenty-seven excited states of and seventeen of have been established by a study of the () reactions in and in . Seven deuteron bombarding energies between 4.75 and 7.5 Mev were used, and the target was a cell with thin windows, containing either natural or -enriched neon gas. The proton groups emitted at 90 degrees were analyzed with a broad-range magnetic spectrograph. The established calibration of the spectrograph, in terms of alpha particles from polonium, together with some well-known reactions, provided the data necessary for precise energy determinations. The values obtained for the ground-state reactions and were 4.534±0.009 Mev and 2.791±0.009 Mev, respectively. Deuteron groups inelastically scattered from and were also observed. The higher energy groups were used in the calibration procedure; the lower energy groups gave the results 4.250±0.008 Mev and 3.356±0.008 Mev for the second excited states of and , respectively. The interpretation of the level schemes of and in terms of the collective model has been considered and is discussed here briefly.
