DI-NEUTRON CORRELATIONS IN LOW-DENSITY NUCLEAR MATTER
Based on the relativistic Hartree-Bogoliubov theory, the influence of the effective interactions in the particle-hole channel on the di-neutron correlations is studied in the nuclear matter. In addition, the evolution of several characteristic quantities of di-neutron correlations, namely, the normal and anomalous density distribution functions as well as the probability density of the neutron Cooper pairs, with the neutron Fermi momentum is discussed.
