Analytical Approximation of Cross Sections of Collisions of Electrons with Inert Gas Atoms

The paper presents an analysis of data on the cross sections of elastic and inelastic collisions of electrons with noble gas atoms. The transport (diffusion) cross section and the excitation and ionization cross sections are considered. Optimal analytical formulas are found for the selected sets of experimental and theoretical data, and approximation coefficients are selected for them. The obtained semi-empirical formulas make it possible to reproduce the cross sections in a wide range of collision energies from 0.001 to 10 000 eV with an accuracy of several percent.
