Fusion and break-up cross section of alpha cluster projectiles on 51V target

Recent development of radioactive isotope accelerators has provided an opportunity to investigate, on the earth, the fusion reaction that forms heavy elements in the cosmos. These involve reactions of nuclei far from stability line, the most exotic of which are very weakly bound. Breakup of weakly bound nuclei is thus an important process in collisions with other nuclei. Cluster type nuclei with small separation energies have a large breakup probability when they interact with a heavy target. As a first step towards the understanding of the small binding energies of cluster type nuclei, it is convenient and quite instructive to induce fusion reactions with the high intensity beam of alpha cluster stable projectile that should have a reasonable breakup probability. The suitable candidates for this kind of study are 20Ne, 12C and 16O that have threshold breakup energies from 4.73 MeV to 7.37 MeV
