Abstract

In this work, the efficacy of fusion cross sections and barrier distributions of 6Li+144,152Sm and 7Li+144,152Sm reactions, as well as the large-angle partial quasi-elastic scattering excitation function and the corresponding barrier distribution for the 6,7Li+144Sm reactions in coupled channel calculation with optical model potential were studied. The results showed that the role of potential and the effect of projectile deformation in these calculations are important parameters. Investigation show that for 6Li+144Sm reaction CDCC calculation has a good agreement with experimental data and for 7Li+144Sm reaction, CCFULL calculation has a good agreement. Forasmuch as the best way to study the behavior of fusion cross section at low energies is the astrophysical S(E) factor, this quantity was used to predict the behavior of 6,7Li+144Sm and 6,7Li+152Sm reactions in energy intervals that the experiment could not be measured. This result predicts the value of energy that the astrophysical S(E) factor had a maximum value, and find the value of S- factor for 6,7Li+144Sm, 6,7Li+152Sm reactions at zero energy by the extrapolation method.
