Abstract
The angular distributions of 13 C elastically scattered by 9 Be nuclei were measured at E Lab ( 13 C) = 16.25 and 19.5 MeV. The measured angular distributions were analyzed via the optical model and the DWBA within the coupled reaction channels methods. In addition to this, the previously obtained data were reanalyzed at energies E Lab = 22.75, 28.12, 36.15, 57.77 and 72.88 MeV. The aim of the study was to elucidate the role of the α -cluster transfer mechanism in the large-angle scattering. As a result of these calculations, the optimal parameters of the potentials and their energy dependence were obtained for 13 C+ 9 Be nuclear system. The data at the backward angles are fairly well reproduced. The spectroscopic amplitudes were extracted for the 13 C → 9 Be + α configuration at various energies. The results are compared with previously reported values. [ABSTRACT FROM AUTHOR]
