General response function with Skyrme’s interaction — •U. Fuhrmann¹ and K. Morawetz² — ¹Fachbereich Physik, Universität Rostock, Universitätsplatz 3, D-18051 Rostock — ²LPC-ISMRA, BLD. Marechal Juin, 14050 Caen and GANIL, Bld, Becquerel, 14076 Caen Cedex 5, France

Linearizing the appropriate kinetic equation we derive general response functions including selfconsistent meanfields and collisional contributions. The latter ones are derived and compared in relaxation time approximation conserving successively different balance equations. The effect of collisions are represented by correlation functions which are possible to calculate with the help of the finite temperature Lindhard RPA expression. The presented results are applicable for finite temperature response of interacting quantum systems if the quasiparticle or meanfield energy is parameterized within Skyrme-type of functionals including density, current and energy dependencies. We present results for collective modes as the giant resonance in nuclei.
