Abstract
Protons from the reaction were analyzed with a magnetic spectrograph. Data were taken at the bombarding energies of 12.0, 13.0, and 14.0 MeV at the observation angles of 60, 90, and 120°. Nine states were found in between the ground state and the 7.35-MeV region of excitation. Excitation energies and uncertainties in keV are 744.1±2, 3105.3±5, 4221.1±3, 6428.1±7, 6539.8±5, 6844.9±5, 6882.4±5, 7097.2±6, and 7351.3±6. Widths of approximately 42 and 61 keV were measured for the levels at 3105.3 and 6428.1 keV, respectively. Uncertainties in excitation energies are reduced by almost an order of magnitude from previous work.
