The effect of breakup on the total fusion reaction cross section of stable weakly bound nuclei

Abstract EN

In the present study, we have performed Coupled-Channel (CC) calculations to study the effect of coupling to the breakup channel on the calculations of the total reaction cross section fus and the fusion barrier distribution at energies near and below the Coulomb barrier Vb for the systems 6Li+209Bi, 7Li+209Bi and 9Be+208Pb.

The inclusion of breakup reaction enhances the calculations of the total reaction cross section in comparison with the recent available experimental data at energies near and below the Coulomb barrier.

The inclusion of breakup channel is found to be very essential and modifies the calculations of the total fusion cross section markedly and describes the experimental data very well below and above the Coulomb barrier.
