    "abstract": "A semiphenomenological approach to the nucleon self-energy in nuclear matter\nat finite temperatures is followed. It combines elements of Thermo Field\nDynamics for the treatment of finite temperature with a model for the\nself-energy, which evaluates the second order diagrams taking the needed\ndynamics of the NN interaction from experiment. The approach proved to be\naccurate at zero temperature to reproduce Im(Sigma) and other properties of\nnucleons in matter. In the present case we apply it to determine Im(Sigma) at\nfinite temperatures. An effective NN cross section is deduced which can be\neasily used in analyses of heavy ion reactions.",
