Abstract

The temperature dependence of the self-energy of a single particle is studied in the surface coupling model. The finite-temperature Green function Matsubara formalism in semi-infinite nuclear matter is applied to the discussion of the damping and the effective mass of the single particle. The calculated results show that the imaginary part of the self-energy of the single particle near the Fermi energy increases linearly with temperature and the characteristic enhancement of the effective mass near the Fermi energy is found to disappear at a temperature T=3 MeV in 208Pb and, correspondingly, the level-density parameter decreases, in agreement with recent empirical data.
