| Abstract: | An experimental determination of the relative intensities of X-ray photoelectron lines corresponding to the inner levels of elements with Z ? 20, and calculations of the total photo-ionization cross-sections for all shells of these elements with the Hartree—Fock—Slater potential are reported. The experimental and theoretical values agree well for the 1s levels while marked discrepancies are revealed for the 2p levels. The theoretical values of the cross sections for the atomic valence levels are used to calculate the relative intensities of molecular levels in CF4, BF4?, BeF42?, LiF, NO3?, CO32?, CO, N2, CO2, H2O and C4H5N. The results of the calculations agree satisfactorily with experiment. |
