Abstract
Detailed cross sections out to 170° c.m. for elastic scattering and the excitation of states in and in have been determined by bombarding targets with 34 MeV beams and targets with beams at the same c.m. energy. The present results show that the direct breakup total cross section for is about 25 times larger than the sequential total cross section to the 4.63 MeV state of . In addition, single neutron and proton stripping angular distributions have been measured. The distorted-wave Born approximation is unsatisfactory for the excitation of the 0.48 MeV state of , the 4.44 MeV state of , and the mutual excitation of these two states. Coupled channels calculations, using the rotation-vibration model, describe the excitation of states in well and find K=3 for the 9.64 MeV state. Poor fits are obtained to the projectile and mutual excitation data with coupled channels calculations. Finite range distorted-wave Born approximation calculations of single-nucleon stripping are in good agreement with the data. Extracted deformation lengths and spectroscopic factors are consistent with those from other studies.
