Abstract
Shell model features are investigated for the Deuterium and 4He with a semirealistic potential, using the Hybrid Multideterminant method applied to the bare Hamiltonian. For a sufficiently large single-particle space we found that few Slater determinants account for most of the binding energy of 4He. Using only one Slater determinant with all symmetries restored with the appropriate projectors to good quantum numbers, we can account for about 84% of the binding energy of 4He.
