摘要：
A distorted-wave Born exchange (DWBE) approximation was used to calculate the electron-impact ionization cross sections and rate coefficients for the ions of Ne+,..., Ne9+. The comparison of the calculated results with the experimental data and other theoretical calculations shows that the DWBE method is valid for all the ions of neon. The results of the calculations for cross sections were fitted by empirical formulae to meet the requirements of applications. A set of improved empirical formulae were developed for the fast and accurate calculations of rate coefficients from the fit parameters of cross sections.
