    "abstract": "The spectral function of pions interacting with a gas of nucleons and\nDelta-33-resonances is investigated using the formalism of Thermo Field\nDynamics. After a discussion of the zero Delta-width approximation at finite\ntemperature, we take into account a constant width of the resonance. Apart from\na full numerical calculation, we give analytical approximations to the pionic\nspectral function including such a width. They are found to be different from\nprevious approximations, and require an increase of the effective Delta-width\nin hot compressed nuclear matter. The results are summarized in an effective\ndispersion relation for interacting pions.",
