Abstract

We present a generalization to finite temperature of Landau's kinetic equation for quasiparticles, and describe its application to the nuclear fragmentation process. With a simple form for the behavior of the interaction function ƒ pp′ , the kinetic equation is solved in the relaxation time approximation. The dispersion relation for sound waves in hot Fermi liquids is derived and explored in regimes of interest: in the hydrodynamic, collisionless and the low temperature limits. Results for the fragmentation of an A = 200 droplet are presented as a function of its initial temperature and density.
