Abstract
The angular distributions of the reaction leading to the 0.95-, 1.67-, 2.62-, 2.72-MeV levels of were measured at an incident deuteron energy of 5.5 MeV. The angular distribution of the elastically scattered deuterons from was also measured. The results were analyzed both by Butler theory and by zero-range distorted-wave Born-approximation calculations. The orbital angular momentum transferred in the reaction was determined to be for these states of . Some measurements were made. The results for the decay of the 1.67-, 2.62-, and 2.72-MeV states were consistent with previous work. The 3.39-MeV level of was found to have a partial width for gamma decay which is less than 10% of the total width. The level structure of is compared with the spectrum of above 15-MeV excitation. Recent angular-distribution measurements of Mingay are used to analyze Doppler-shift measurements of Warburton and Chase for the 1.67- and 2.62-MeV levels. The result is limits of less than sec on the mean lifetimes of both states.
