    "abstract": "We investigate the response function of hot nuclear matter to a small\nisovector external field using a simplified Skyrme interaction reproducing the\nvalue of the symmetry energy coefficient.\n  We consider values of the momentum transfer corresponding to the dipole\noscillation in heavy nuclei. We find that while at zero temperature the\nparticle hole interaction is almost repulsive enough to have a sharp (zero\nsound type) collective oscillation, such is no longer the case at temperatures\nof a few MeV. As a result a broadening of the dipole resonance occurs, leading\nto its quasi disappearence by the time the temperature reaches 5 MeV. The\nsensivity of the temperature evolution of the width when modifying the residual\ninteraction strength is also examined.",
