摘要:
Statistical moments of the relativistic Maxwell−Boltzmann momentum distribution are obtained from integral representations of modified Bessel functions. Approximate low temperature (m/kT≫1) behaviors for the mean and mean−square momenta are indicated via asymptotic expansions of corresponding Bessel functions and the results are briefly contrasted with the usual classical predictions. The most probable momentum is also discussed.
