Sub-Coulomb barrier penetration for a 6Li with a clustered and deformed ground-state

The penetrability of the Coulomb barrier of 6Li by a proton is studied using a quantum cluster model. We focus on the role of quadrupole deformations in the nucleus ground-state, in terms of which a 6Li–p form factor with tensor components is computed. We find that the diagonal part of the tensor te...

Description
Summary:The penetrability of the Coulomb barrier of 6Li by a proton is studied using a quantum cluster model. We focus on the role of quadrupole deformations in the nucleus ground-state, in terms of which a 6Li–p form factor with tensor components is computed. We find that the diagonal part of the tensor term reduces the average barrier penetrability of the system. However, the tensor interaction due only to the mechanism studied at present is very small, regardless of the specific adopted construction, and yields negligible effects.
