Abstract: New parameters for the calculation of L subshell ionization cross sections using a semiempirical expression are presented. The parameters were obtained by fitting an analytical function to the experimentally obtained values of L subshell ionization cross sections. The experimental data included compilation of the published data from 1975 to 1982 by Sokhi and Crumpton as well as our newly compiled data published in 1982-1991. The number of data employed for the fitting was 2295, 3 1 2 times more than that used in Miyagawa's work. The data were divided into six groups according to the Z values: 14 ≤ Z ≤ 42, 43 ≤ Z ≤ 50, 51 ≤ Z ≤ 60, 61 ≤ Z ≤70, 71 ≤ Z ≤ 80 and 81 ≤ Z ≤ 92. Each was fitted by the analytical function to obtain the parameters for the calculation of L1, L2 and L3 subshell ionization cross sections. For data in the group with Z ≤ 42, only parameters for the calculation of L total ionization cross sections were determined. A comparison of the various theoretical predictions with the experimental data and the fits is also presented. © 1993.
