To Study the effect of nuclear potential parameters on fusion cross-section of 7Li with 64Ni

Abstract

The aim of this work is to scout or explore the dependence of the fusion cross-sections on various parameters such as depth of the potential, radius and the diffusion parameter. The effect of these parameters is explored at above and below the coulomb barrier by taking loosely bound nuclei 7Li as projectile and isotope of nickel that is 64Ni which is a stable mass target. The CCFULL program is used to determine the fusion cross-section and mean angular momentum of the compound nucleus, taking into account the no-Coriolis approximations to reduce the dimensions of the coupled channel calculations. The program input parameters are given to the computer code CCFULL and the test shows the fusion cross-section for the 7Li + 64Ni reaction. In the first case, the projectile and the target nuclei are assumed to be spherical and measure the fusion cross-section in the absence of channel coupling. In the next case, the target is assumed to be deformed which effect the fusion cross-section. Any variation in the above three parameters affect the barrier height, the shape and depth of the potential pocket which effect the fusion cross-section of 7Li + 64Ni reaction.
