A new semiempirical model comprising few important features of the DM model of Deutsch et al. (Int J Mass Spectrom 1998, 177, 47) and the widely used empirical model of Bell et al. (J Phys Chem Ref Data 1983, 12, 891) has been proposed. The proposed model has been examined to evaluate the electron impact K ‐shell ionization cross sections of 30 atomic targets ranging from H to U ( Z = 1–92) and found to describe with considerable success the experimental results over a wide range of incident energies up to 2 GeV using a single set of species independent parameters. © 2008 Wiley Periodicals, Inc.
