Query: Self-consistent solution of Galitskii-Feynman equations at finite
  temperature   We solve the in-medium T-matrix equation at finite temperature including the
off-shell propagation of nucleons. In this way a self-consistent spectral
function for the nucleons is obtained. The results are compared to a
calculation using the quasiparticle approximation in the T-matrix equation.
Also the effective in-medium cross sections for the two cases are compared.
