摘要
We use a separable form of the Paris nucleon-nucleon interaction to calculate nucleon self-energies and spectral functions at the saturation density of symmetric nuclear matter at finite temperature. The behaviour of these quantities at temperatures above and close to the critical temperature for the superfluid phase transition in nuclear matter is investigated. From the self-energy the spectral function and occupation numbers at finite temperature are calculated. The sensitivity of the results for the realistic nucleon-nucleon potential to details of the interaction potential is studied by a comparison to an exploratory calculation previously done for the purely attractive Yamaguchi potential.
