Abstract
Differential cross sections have been obtained for the elastic scattering of from at 4.0, 6.0, and 8.0 MeV. The results obtained at 6.0 and 8.0 MeV were fitted using optical potentials. Measurements on the reaction were made on resolved alpha-particle groups leading to states in at 3.06 and 3.13 MeV. Excitation functions were obtained in the incident energy range from 4.0 to 10.1 MeV at laboratory angles of 20°, 50°, 130°, and 170°. Differential cross sections as a function of angle were obtained at 4.0, 6.0, and 8.0 MeV. Zero-range distorted-wave Born-approximation calculations were made assuming pickup as the dominant mechanism. The 3.13-MeV level in has been assigned a negative parity, that at 3.06 MeV has been assigned a positive parity. The ratio of spectroscopic factors obtained for these two levels is approximately equal to 1.
