Effect of Tensor Force on the Halo Structure of 29Ne and 31Ne

Abstract

The structure of Ne isotopes has been investigated by using deformed Skyrme—Hartree—Fock (SHF) method and BCS approximation. Especially the effect of tensor force on the halo structure of 29Ne and 31Ne is discussed. To this end, the tensor contributions are considered to the energy density function and the single particle potential in SHF theory. For comparison, four Skyrme interactions are used: SLy5 and SGII without tensor force, and SLy5+T and SGII+T with tensor force. The results indicate that the inclusion of tensor force shows a more pronounced halo structure for 31Ne.
