Abstract
Angular distributions in the elastic scattering of B-8 from C-12 and Ni-58 targets at different energies have been analyzed in the framework of the double-folding (DF) optical model. The real central part of the nuclear optical potential is obtained by folding the M3Y effective interaction with the cluster density distribution of the B-8 nucleus. The experimental angular distributions have been successfully reproduced. This confirms the validity of the cluster structure of the B-8 nucleus.
