Abstract
Transport coefficients of charged particles undergoing both elastic and inelastic collisions with a gas of neutral molecules are calculated using momentum-transfer theory. A criterion is obtained for the phenomenon of negative differential conductivity (i.e. the drift velocity decreasing with applied electric field) and the well-known generalized Einstein relation is appropriately modified.Keywords
