“…Other authors used the method of Thompson et al to evaluate breakup polarization potentials for different systems [114,206,207]. Santra et al [114] calculated the dynamic polarization potential due to direct breakup of 6 Li, in the 6 Li- 209 Bi collision at near-barrier energies. They found that the real part of the polarization potential is repulsive, leading to a higher fusion barrier, and the imaginary part is absorptive and has a long-range.…”

Abstract.The fusion excitation and elastic angular distribution were measured for 6,7 Li+ 28 Si from below to above Coulomb barrier (≤ 3V b ) energies. The barrier distribution derived from the fusion data was found to be broad and asymmetric at the sub-barrier region, compared to 1D BPM estimation. Effect of rotational coupling on fusion was found to be not so dominant. Phenomenological optical potential parameters, with surface and volume type imaginary potentials, were obtained from f tting of elastic scattering data and energy dependence of real and imaginary surface strengths were investigated around the barrier. CDCC calculations considering only breakup of projectile were performed for 6,7 Li+ 28 Si with the elastic scattering data, using the code FRESCO. The effects of breakup of projectile on elastic cross section do not agree with the energy dependence of real and imaginary strength with volume type imaginary potential around the barrier.

“…Suppression of complete fusion, breakup threshold anomaly in optical potential describing elastic scattering, large production of alpha particles in the reactions and larger peak to valley ratio of the fission fragment mass distribution at sub/near barrier energies are some of those interesting observations [1][2][3][4]. Projectile breakup in the field of a target nucleus is known to play an important role in the manifestation of all the above features.…”

Elastic, inelastic and inclusive alpha cross sections have been measured. Coupled-channels calculations by including the couplings of projectile breakup channels and target excitations explain the measured elastic and inelastic data. The inclusive alpha particle production is found to be more than two-third of the total reaction cross section. From coupled-channels calculations, the contribution of α from the non-capture α-d breakup of the 6 Li projectile is calculated to be very small. It suggests the possibility of many transfer induced breakup channels, having α as one of the breakup fragments, to be responsible for such a large α particle production.
