The quadruple deformation effects of ⁹Be in heavy-ion reactions

Abstract

The effects of the projectile deformation and orientation on the total potential characteristic have been studied for the reactions between weakly bound nucleus, 9Be, as the projectile and different targets. In this paper, the double-folding model is used to calculate the nuclear potentials and deformation of projectile included. It is shown that applying the deformation effects can modify the potential barrier height and depth in the interior regions of the potential. It is also shown that the gradient variation of the potential barrier height is linearly increased when the angle between the projectile and the target nuclei increases. The rate of the variation is constant in different reactions with 9Be. In order to study the possible effect of these deformation dependent potentials, application is made in the calculation of cross-sections of the different reactions. It is observed that the deformation and orientation are of important role in the dynamics of such reactions and improve the agreement with the experimental results.
