Abstract : Momentum transfer cross sections for electrons in He, Ar, Kr, and Xe are obtained from a comparison of theoretical and experimental values of the drift velocities and of the ratio of the diffusion coefficient to the mobility coefficient for electrons in these gases. The theoretical transport coefficients are obtained by calculating accurate electron energy distribution functions for energies below excitation using an assumed energy dependent momentum transfer cross section. Resulting theoretical values are compared with the available experimental data and adjustments made in the assumed cross sections until good agreement is obtained. (Author)
