Excitation functions for the elastic scattering of protons by 22 Ne have been measured at 90°, 105°, 120°, 135°, 150°, and 160° from 0.8 to 3.13 MeV, and for the reaction 22 Ne(^') 22 Ne* (first excited state), at 90°, 120°, and 150° from 2.0 to 3.13 MeV, with an average energy resolution of about 250 eV. Spins, parities, and partial and total widths have been extracted for the large majority of the 76 resonances observed. Two isobaric analog states, those of the sixth and seventh excited states of 23 Ne, have been identified. Both analogs are evidenced as fragmentations of the broad T > states into enhancement of the background T< states. A sum rule applied to the individual fine-structure widths implies spectroscopic factors in agreement with those extracted from (d,p) stripping measurements on 22 Ne.

Fission yields have been calculated assuming as a first approximation that they are proportional to the product of the level densities of a pair of binary fission products. The level densities have been calculated with the simplified shell-model methods of Newson and Duncan. The calculations predict a single symmetric peak when the mass of the fissioning nucleus, AoS2, 2850, or after neutron emission, 77132. (2) We define (binary) symmetric fission by: 28
