Abstract
Excitation functions and angular distributions of the radiation from following the reaction have been measured with a 56- Ge(Li) detector in the range from 5.4- to 7.8-MeV bombarding energy. At 6.00-, 6.16-, 7.28-, and 7.45-MeV bombarding energy, resonances in several neutron channels were observed which were attributed to isobaric analog states in the compound system . From an analysis of the 6.16-MeV resonance in terms of Robson's theory, the level shift keV was obtained which was compared with an estimate derived from the spreading width of this resonance. New states in were identified at 1834-, 2081-, 2130-, 2220-, 2298-, 2389-, 2570-, and 2610-keV excitation energy. From a Hauser-Feshbach analysis of the -ray excitation functions and angular distributions, the spins of a number of these states and mixing ratios of -ray transitions were found. Evidence is given for a weak coupling multiplet of a neutron hole coupled to the 2.18-MeV state in .
