N2 - A new method unifying many and few-body aspects of nuclear structure has recently been introduced (Hove et al. in J Phys G Nucl Part Phys 45:073001, 2018). This method combines the many-body description of a core and the few-body structure of this core surrounded by two valence nucleons. For this reason this method is expected to work specially well when applied to nuclei close to the driplines, where the few-body halo structure with one or more nucleons outside the core is established. In this work we apply the new method to nuclei close to the valley of stability, with 42Ca and 50Ca as illustrations.

We find that the unified method provides results rather similar, although distinguishable, to the Hartree–Fock calculations.
