  text: A nonequilibrium occupation distribution relaxes towards the Fermi-Dirac distribution
    due to electron-electron scattering even in finite Fermi systems. The dynamic
    evolution of this thermalization process assumed to result from an optical excitation
    is investigated numerically by solving a Boltzmann equation for the carrier populations
    using a one-dimensional disordered system. We focus on the short-time-scale behavior.
    The logarithmically long time scale associated with the glassy behavior of interacting
    electrons in disordered systems is not treated in our investigation. For weak
    disorder and short range interaction we recover the expected result that the relaxation
    rate is enhanced by disorder. For sufficiently strong disorder, however, we find
    an opposite trend due to the reduction of scattering probabilities originating
    from the strong localization of the single-particle states. Long-range interaction
    in this regime produces a similar effect. The relaxation rate is found to scale
    with the interaction strength, however, the interplay between the implicit and
    the explicit character of the interaction produces an anomalous exponent.
