Kinetics of hot electrons in quantizing magnetic fields. II. Diffusion approximation

The nonequilibrium statistical operator method is used to derive a system of balance equations for the momentum density and particle number in the energy space. This system determines the kinetics of hot electrons in strong crossed electric and magnetic fields. For quasielastic scattering the equations are transformed into differential equations that describe the diffusion of electrons in the energy space; they are integrated in the lowest approximation in the ratio of the relaxation frequency of the transverse momentum to the frequency of the cyclotron motion.
