Electron velocity distribution and transport properties under an electric field have been analysed by the Boltzmann equation giving the flow-in rate with a scalar number of the momentum transfer collision frequency v_m(υ). This is equivalent to treat electrons as if they are isotropically scattered with v_m(υ) in spite of the fact being anisotropically scattered. Maintaining the momentum transfer cross section constant with the change of anisotropy in the elastic scattering, the validity of such pseudo-isotropic analyses has been examined by the extended FTI method assuming a simple model anisotropy. The results show that the transverse diffusion coefficient take erroneous values in the usual pseudo-isotropic analyses so far conveniently used.
