Study of ^9 Be fusion in ^93 Nb near the Coulomb barrier

The measurement of fusion cross sections from the ^9 Be induced reaction on ^93 Nb within the energy range of 20–46 MeV has been conducted using off-beam γ -ray spectroscopy. The measured excitation functions have been analyzed using equilibrium and pre-equilibrium reaction-based model codes to understand the underlying mechanisms. Additionally, the measured fusion excitation function was examined within the framework of the coupled-channel approach using the CCFULL code. Notably, the coupled-channel calculations, including couplings to inelastic states of the target and the projectile, yielded a satisfactory description of the sub-barrier fusion data. However, at energies above the barrier, the fusion cross section was observed to be suppressed by approximately 17
