In-medium nucleon-nucleon potentials in configuration space

摘要: Based on the thermodynamic Green function approach two-nucleon correlations in nuclear matter at finite temperatures are revisited. To this end, we derive phase equivalent effective $r$-space potentials that include effect of Pauli blocking a given temperature and density. These enter into Schr\"odinger equation is representation Galitskii-Feynman for two nucleons. We explore analytical structure complex $k$-plane by means Jost functions. find despite Mott correlation with deuteron quantum numbers manifested as antibound states, i.e., zeros negative imaginary axis momentum space. The analysis presented here also suited Coulombic systems.
