Abstract

Heavy-ion induced fission fragment angular distribution measurements performed in recent years have provided interesting results. From a systematic study involving several projectiles and actinide targets, the entrance channel mass asymmetry dependence of fission anisotropies has been brought out at energies above the fusion barrier. It has been observed that the fission fragment anisotropies, essentially for all target - projectile combinations involving actinide targets increase as bombarding energy is lowered below the barrier and are anomalously large when compared to the saddle-point model expectations. However, similar measurements carried out for spherical targets are consistent with the calculations based on the saddle-point model.
