Abstract:
Study of reaction mechanisms with weakly bound nuclei is of interest to understand the dynamics of nuclei near the drip lines and also to understand nucleo-synthesis processes. Due to the low breakup threshold energies of these nuclei it is expected that the breakup channel would have a significant effect on different reaction channels. This has been rigorously investigated in the last two decades from which two main observations- the breakup threshold anomaly in the optical model potential and the suppression of complete fusion cross-sections as compared to model calculations, have been found. In the presentation, experiments carried out with the weakly bound 9Be projectile and a medium mass 89Y target, to investigate the effect of breakup of 9Be on the elastic and fusion channels, will be presented.
