Contribution of Nuclear Field Theory medium effects to the pairing gap
(2011) 13th Conference on Theoretical Nuclear Physics in Italy In Journal of Physics: Conference Series 336.- 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)

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