Abstract

The Boltzmann collision term with the Uehling-Uhlenbeck-Nordheim modification for fermion statistics is computed in nuclear matter. The initial distribution function is in momentum space either two Fermi spheres separated by a relative momentum as in a collision between two heavy ions or some other specified deformation. Relaxation times for the equilibration is obtained as a function of density and final temperature of the equilibrated system. The mode dependence of the relaxation times is calculated by expanding the angular dependence of the distribution in spherical harmonics. Transport coefficients for viscosity and thermal conductivity are also calculated as well as their temperature and density dependences.
