Abstract
Elastic scattering cross sections for 10–170° c.m. have been measured for 7Li+ 11B and 7Li + 13C at 34 MeV. These data have been analyzed with the optical model using Woods-Saxon potentials, or potentials with a double-folded real part. The double-folded potentials were found to fit the data better, and quadrupole contributions were required to fit the large angle 7Li+ 11B data. In addition angular distributions for the ( 7Li, 8Li), ( 7Li, 6Li) and ( 7Li, 6He) reactions were measured. The transfer data were analyzed with finite-range DWBA calculations which were able to describe the shape of the data well and produced spectroscopic factors in agreement with theoretical and other experimental values. A phase shift of about 3° between the calculations and the data was found for the ( 7Li, 6Li) and ( 7Li, 6He) reactions.
