Abstract:
Data for momentum transfer cross-sections for electron scattering by Cs, Na, K, Li, OH, CO, $\mathrm H_2$, $\mathrm N_2$, $\mathrm H_2\mathrm O$, $\mathrm{CO}_2$, H, O, N, $\mathrm O_2$, $\mathrm N_2\mathrm O$ are approximated by cubic mean-square splines. Maximal error of approximations is no more than 5%, mean-square $\sim1\%$. Splines are given in piecewise polynomial form. Approximations may be used in computations of various transport coefficients and/or as a reference data.
