Description
The low-energy heavy ion fusion reactions play a crucial role in elucidating various aspects of nuclear physics as well as astrophysics. The dynamics of these heavy-ion fusion reactions depend upon the internal structure properties such as the deformations of the interacting target and projectile nuclei [1]. This study aims to explore the influence of nuclear shape degrees of freedom on the fusion mechanism within the relativistic mean-field (RMF) approach [2]. The nuclear interaction potential is obtained by folding the well-known M3Y effective nucleon-nucleon (NN) potential with the axially deformed RMF densities [2]. The fusion barrier characteristics such as the barrier position and height are obtained at different orientations for the deformed $^{154}$Sm target nucleus fused with spherical $^{16}$O projectile. The fusion and/or capture cross-section is obtained within the Wong model [3] and the results are compared with the available experimental data [4]. The barrier characteristics and consequently the cross-section is observed to be significantly affected by the quadrupole deformation as well as the orientation of the target nucleus.
