| Abstract: | The temperature dependence of the self-energy of a particle is studied in semi-infinite nuclear matter by making use of interactions constrained by self-consistency. Using the finite temperature Green's function Matsubara formulism, and applying the theory of slab model to the single-particle states in 208Pb, the calculated results show that the imaginary parts of the self-energy of a particle at Fermi energy linearly increase with the increase of temperature. |
