Abstract

The excitation energies of ^6,8He and ^8,10,12B isotopes in the p-shell region have been calculated by using large-basis no-core (i.e. considering all nucleons active with partial restrictions imposed on some nucleons). The shell model calculations have been performed using spsdpf model space with wbt effective residual interaction fitted for the p-shell nuclei. Three set of restrictions have been imposed named in our calculations have been used. The comparison of our theoretical work with the recent available experimental data shows that the restriction gives best results for Helium isotopes while is in better agreement with the experiment for Boron isotopes.
