Fusion studies for ⁶Li+ and ⁸²Se, ⁵¹V systems using ion beam gamma-ray spectroscopy

Complete fusion cross-section for weakly bound nuclei are suppressed above coulomb barrier compared to one Dimensional Barrier Penetration Model and coupled channel calculations. The suppression is partially understood in terms of loss of flux due to projectile breakup before fusion and/or due several partial fusion channels. Several experiments and theoretical calculations are carried out in recent past and systematic study suggests a universal suppression of complete fusion along mass. Though, few experimental data suggests much lower suppression factor at lower mass region and others suggest slight lower suppression. In view of this we have measured fusion cross-sections for ⁶Li+⁸²Se and ⁶Li+⁵¹V systems using InBeam γ-spectroscopy method. Preliminary results are presented here along with statistical model calculations using PACE
