Abstract

The paper presents an analysis of data on the cross sections for ionization of noble gas atoms by electron impact. For the selected sets of experimental and theoretical data an analytical formula is proposed, based on separate accounting for the knockout of electrons from the outer and inner shells, and the corresponding approximation coefficients are selected. The obtained semi-empirical formula reproduces the values of the ionization cross sections in a wide range of energies with an accuracy of several percent. The analysis of the approximation coefficients makes it possible to reduce the influence of errors in the initial experimental data and significantly increase the accuracy of estimating the ionization cross sections.
