Comparative Calculation of Electron Transport Properties in Anisotropic Ramp Model Gas of Reid by Monte-Carlo Simulation

Abstract

Adopting the model differential cross sections used by Reid (1979) and by Haddad et al. (1981), an investigation to asses the discrepancies observed in the transverse diffusion coefficients D_T and other transport properties are performed by the Monte-Carlo simulation. The results show that the values of ND_T drastically vary with the change of anisotropy in the scattering property against the common sense that ND_T is determined solely by the reduced field E/N under a given momentum transfer cross section. Cross sections so far derived from the D_T/μ data may be necessary to be reassesed if anisotropy in the scattering properties is considered.
