Description
We present an extension of the Discrete Non-Orthogonal Shell Model [1, 2] within a Variation After Projection approach [3] recently developed at IPHC, Strasbourg. This method is an alternative to the exact shell-model diagonalization [4] using non-orthogonal many-body expansions combined with symmetry restoration techniques [5]. We discuss the prospective of the new method for applications in different regions from mid-mass to superheavy nuclei [6].
