Role of surface energy coefficients in fusion with weakly bound projectile

In the present study we are attempting to investigate the influence of surface energy coefficients ("γ-MS,γ-MN1976,γ-MN1995,γ-MSNew" ) on the fusion systems including weakly bound projectiles. This interaction potential is calculated using proximity potential AW95 as well as three body dynamic classical trajectory to calculate fusion cross section. Our obtained results reveal that among the four surface energy coefficients, "γ-MS" leads to a shallow potential compared to other sets of "γ" , whereas "γ-MN1976" leads to the deepest potential as well as the barrier height of potential of "γ-MN1976" is better agreement with experimental data. Also complete fusion cross section of "γ-MS" surface energy is better agreement with experimental data while in the incomplete fusion cross section, the "γ-MN1976" can reproduce the experimental data well.
