Abstract
The interaction of /sup 9/Be ions with /sup 28/Si target nuclei was investigated by measuring elastic scattering cross sections and evaporation spectra. The behavior of the elastic scattering cross sections as a function of the classical distance of closest approach indicates a localization of direct reaction processes in the far tail region of the interaction potential, whereas fusion with compound nucleus formation sets in at considerably shorter distances. A statistical model analysis of the evaporation spectra led to a value of sigma/sub fu/ = 735 mb for the fusion cross section, whereas the total reaction cross section as determined from the elastic scattering data amounts to sigma/sub R/ = 1120 mb. This difference is a peculiar phenomenon of the very weakly bound /sup 9/Be system.
