ABSTRACT: This paper addresses the effects of nuclear
properties at different potentials. Reid Soft Core (RSC) and Nijmegen
potentials were used to study the nuclear system of 4He nucleus. It
has been examined with and without large compression. Moreover, the constrained
spherical Hartree-Fock (CSHF) approximations are used as a major tool of
analysis. The dependence of the ground state properties was investigated to the
degree of compression. It was noticed that it is possible to compress the
nucleus to a smaller volume and the nucleus becomes more bounded using RSC than
Nijmegen potential. It was also shown that the spectrum of single particle
levels increases more rapidly for Nijmegen than RSC potential under
compression. Finally, the radial density distribution remains constant, except
in the interior region, while it is larger with RSC than Nijmegen potential. At
large compression, the radial density distribution becomes larger than that in
the interior region when RSC potential is used.
