Scientific paper

We solve the Boltzmann equation for the evolution of mu and tau-type neutrino distribution functions including contributions from electron scattering, electron-positron annihilation, nucleon-nucleon bremsstrahlung, and nucleon scattering at temperatures and densities relevant to supernova and protoneutron star calculations, but in an idealized system with no spatial or angular gradients. We incorporate the structure function formalism of Reddy et al. (1998) and Burrows and Sawyer (1998) in electron scattering and nucleon scattering, respectively, in order to include the full scattering kinematics at arbitrary degeneracy. Particularly, we examine the timescales for thermalization with the ambient nuclear medium and the approach to equilibrium.
