Structural study of stable (4He) and Halo (6He, 8He) helium isotopes using Skyrme pairing force-SKP modified SKM* and SLy4 functionals.

In this work, Nuclear Energy Density Functional Theory (NEDFT) has been used to investigate the various structural properties of stable and weakly bound and/or Halo structure nuclei. The different Skyrme interactions like SKM*, SKP Sly4 are utilized to study the structural properties of 4He, 6He and 8He nuclei. Further all the density functionals predict approximately similar behaviors for these nuclei and the calculations based on adopted Skyrme interactions indicate that 6He and 8He nuclei exhibits neutron halo structure.
