Realistic effective interactions for halo nuclei [link]Paper  doi  abstract   bibtex   
We study halo nuclei using a two-frequency shell-model approach employing wave functions of two different oscillator constants ℏ$\omega$in and ℏ$\omega$out, the former for the inner orbits and the latter for the halo (outer) orbits. An initial application has been made for the halo nuclei 6He and 6Li, with OS1/2 taken as the inner and (Op3/2, Op1/2) as the halo orbits. Starting from the Paris NN interaction, we have derived a G-matrix folded-diagram effective interaction for this two-frequency model space, using an essentially exact treatment for the Pauli exclusion operator for the G-matrix. While keeping ℏ$\omega$in fixed, we have performed calculations with different choices for ℏ$\omega$out, treating it as a variation parameter. For ℏ$\omega$in = 19.7 MeV and ℏ$\omega$out = 8.2 MeV, our calculated valence energies for 6He and 6Li are -2.77 and -3.55 MeV, respectively, both in good agreement with experiments. The importance of certain three-body-force diagrams is discussed.
