Abstract :
Coincidence measurements of α-12C pairs collinearly emitted in the breakup of 30 MeV/u- 16O incident on 208Pb and 120Sn were performed with a two detector system set up along the focal plane of a magnetic spectrograph. Double differential cross sections for sequential breakup via the 22+ and 23+ states in 16O were analyzed within the framework of coupled-channels (CC) calculations which incorporated microscopic α-12C cluster model wave functions for bound and unbound states of 16O. The experimental data are satisfactorily reproduced by the CC calculations to within a factor of two. The results are discussed in terms of the interference between nuclear- and Coulomb-breakup amplitudes.
