The total cross sections of electron-impact single-K-shell ionization of 14 atomic targets ranging from H to U (1{<=}Z{<=}92) are calculated using a modified version of the BELI formula [Bell et al., J. Phys. Chem. Ref. Data 12, 891 (1983)] by incorporating both ionic and relativistic corrections in it. The proposed modified Bell model with a single set of parameters is found to provide an excellent description of the experimental data in the reduced energy range 1{<=}E/I{sub K}{<=}10{sup 6} (E and I{sub K} are, respectively, the incident energy and ionization potential) with a performance level at least as good as any of the existing methods and models.
