Effect of tensor force on the halo structure of ²⁹Ne and ³¹Ne

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.
