Abstract
Angular distributions of the elastic and breakup cross sections of 42 MeV L i-7-projectile on Ni-58 target are measured at wide angles beyond the grazi ng angle. Coincidence measurements are done at unequal angle pairs. In this angular region, the direct breakup is found to be very small and strongly dominated by the nuclear breakup process, while the sequential breakup cont ributions from the decay of the 7/2(-), 4.63 MeV resonant state of Li-7 rem ain significantly large within its corresponding sequential cone. Some indi cations of contributions from the higher sequential states (5/2(-) 6.68 MeV , 5/2(-) 7.46 MeV) are found. (C) 1999 Elsevier Science B.V.
