The electron drift velocities and corresponding mean energies have been calculated numerically using an approximate two-term solution of the Boltzmann transport equation for Ar/N{sub 2} gas mixtures at electric field-to-gas density ratios (E/N) below 2.0{times}10{sup {minus}20} Vm{sup 2} (20 Td) and for He/Kr mixtures at E/N below 5.0{times}10{sup {minus}21} Vm{sup 2} (5.0 Td). The results are compared with predictions obtained from a method proposed by Chiflikian based on an {open_quotes}analog of Blanc`s law{close_quotes} [Phys. Plasmas {bold 2}, 3902 (1995)]. Large differences are found between the results derived from the Blanc`s law method and those found here from solutions of the transport equation that indicate serious errors and limitations associated with use of the Blanc`s law method to compute drift velocities in gas mixtures. {copyright} {ital 1997 American Institute of Physics.}
