Abstract

We calculate the different contributions to the pairing gap for the case of the superfluid nucleus 120Sn, making use of the Dyson equation (also known as the Nambu-Gor'kov equation in the case of superfluid systems) to propagate leading medium polarization Nuclear Field Theory (NFT) processes to all orders. Starting from a mean field obtained with the SLy4 effective force (mk ≈ 0.7), we renormalize the single-particle states and the pairing gap obtained from 1S0 component of the Argonne v14 N - N interaction, through the interweaving of single-particle motion and collective vibrations of the system. The results provide a detailed description of the fragmentation of the quasiparticle... (More)

We calculate the different contributions to the pairing gap for the case of the superfluid nucleus 120Sn, making use of the Dyson equation (also known as the Nambu-Gor'kov equation in the case of superfluid systems) to propagate leading medium polarization Nuclear Field Theory (NFT) processes to all orders.

The results provide a detailed description of the fragmentation of the quasiparticle strength and of the state-dependent pairing gap.
