Abstract :
Summary form only given. This paper reports the results of investigation of the effects of anisotropic scattering on electron transport coefficients in carbon tetrafluoride (CF/sub 4/) Our choice of a set of cross sections is based on a critical survey of differential and integral cross sections published recently by Christophorou et al. (1996). To describe the available differential elastic scattering determinations for electrons in CF/sub 4/ we developed analytical fits to these data, which are useful for Monte Carlo (MC) calculations. For this purpose, the most convenient method of tabulating the differential scattering data is the analysis of various experimental and theoretical determinations in terms of phenomenological extension of the screened Rutherford formula.
