Abstract

We investigate the impact of the 6Li ground-state deformation on Coulomb-barrier penetrability in nuclear reactions between 6Li and a structureless projectile. The 6Li ground state is described through a quantum di-cluster model, including a quadrupolar component which induces a tensor term in the projectiletarget interaction. The corresponding ground-state form factor, for each possible 6Li orientation, is employed as a potential barrier in a Wentzel-Kramers-BrillouinJeffreys (WKB) radial penetrability calculation. The formalism was applied to the 6Li–p scattering. Throughout the sub-Coulomb energy range, we find no significant influence of the tensor interaction on the overall penetrability.
