Abstract
Fission fragment mass distribution has been measured from the decay of Bk nucleus populating via two entrance channels with slight difference in mass asymmetries but belonging on either side of the Businaro Gallone mass asymmetry parameter. Both the target nuclei were deformed. Near the Coulomb barrier, at similar excitation energies the width of the fission fragment mass distribution was found to be drastically different for the N + Th reaction compared to the B + U reaction. The entrance channel mass asymmetry was found to affect the fusion process sharply.
