Erratum to “Cross sections for ionization of K, L and M shells of atoms by impact of electrons and positrons with energies up to 1 GeV. Analytical formulas” [At. Data Nucl. Data Tables 95 (2009) 871–909

Abstract

Table 1 contains two incomplete entries. Values of the coefficient a5 for Z 1⁄4 36 and 37 (for the M1 subshell) should be 4.301E 2 and 1.070E 1, respectively. We thank Dr. Chrystel Hombourger for pointing out these misprints. The statement ‘‘To correct partially for this shift we can use the analytical formulas (2) and (4) with the experimental value of the ionization energy in the definition of the overvoltage” (page 874, starting at the end of the left column) is incorrect. The numerical ionization cross sections used in the fits with the analytical formulas were calculated from the Dirac–Fock–Slater potential and, consistently, the ionization energies, En‘j, given in the tables are the eigenvalues of the radial Dirac–Fock–Slater equations. These ionization energies are also used in the Fortran subroutines provided as supplementary material in the online ver-
