Electron Impact K-shell Ionization Cross Sections

A new semi-empirical model comprising few important features of the DM [1] model and Bell [2] model is used to evaluate the electron impact K-shell ionization cross sections of 30 atomic targets ranging from H to U (Z=1-92). Details results will be presented at the conference [1] H. Deutsh, K. Becker, T. D. Mark, Int. J. Mass Spect. 177, 47 (1998). [2] K. L. Bell, H. B. Gilbody, J. G. Hughes, A. E. Kingston and F. J. J.
