Adiabatic and coupled channels calculations for near barrier fusion of OU using realistic nucleon-nucleon interaction.

We investigate the fusion cross-section and the fusion barrier distribution of OU at near- and sub-barrier energies. We use an interaction potential generated by the semi-microscopic double folding model-based on density dependent (DD) form of the realistic Michigan-three-Yukawa (M3Y) Reid nucleon-nucleon (NN) interaction. We studied the role of both the static and dynamic deformations of the target nucleus on the fusion process. Rotational and vibrational degrees of freedom of U-nucleus are considered. We found that the deformation and the octupole vibrations in U enhance its sub-barrier fusion cross-section. The signature of the the octupole vibrational modes of U appears clearly in its fusion barrier distribution profile. [ABSTRACT FROM AUTHOR]
