摘要：
We introduce a linear Boltzmann equation governing the evolution of charged structureless particles scattering inelastically with heavy field particles. External electric and magnetic fields are accounted for. Conservation of mass as well as balance equations for momentum and energy transfer are discussed in the Lorentz gas limit. A multigroup approximation based on the method of weighted residuals is presented. This approach incorporates external fields in a natural manner. A P1 approximation of the multigroup equations is applied to simple test cases.
