“…Figure 6 shows the partial cross section which can be fitted to a power law with an exponent of three. However, the ions again are formed in different electronic states which can be separated by the help of a single-electron-capture reaction in argon (Binder et al 1987). The energy spectra of doubly charged ions yield information on the electronic state of the primary Ar3+ ion.…”

Multiple ionisation of Ar atoms by single-electron impact is investigated in the energy range from threshold up to about 600 eV. Partial cross sections for the production of Art'+ with 3 C q C 6 are measured. In the near-threshold region the ionisation curves can be fitted according to power laws r K ( E c , -E,,,,)", where the exponmt K is found to be smaller than q for high charge states. At higher electron energies the ionisation cross sections show a significant influence of inner-shell ionisation, which becomes the dominant mechanism for the production of high charge states.

This paper is dedicated to Professor Arthur S. Perlin on the occasion of his 67th birthdayYUFEI GUO and M. A. WHITEHEAD. Can. J. Chem. 68, 989 (1990). The self-interaction-corrected generalized exchange local-spin-density functional theory (LSD-GX-SIC) with Gopinathan, Whitehead, and Bogdanovic (GWB) Ferrni-hole exchange parameters is used tocalculate the ionization potentials of the multiply charged ions for the elements C, Al, C1, Ar, Ca, Fe, and Br. The effect of the correlation correction on the ionization potentials is considered. The calculated ionization potentials are compared with Hartree-Fock, recent Xa, and experiment. The correlation correction is important in the calculations. The results in the LSD-GX-SIC theory with GWB Fermi-hole exchange parameters and the Vosko, Wilk, and Nusair correlation correction are in excellent agreement with experiment. The LSD-GX-SIC theory can predict unknown ionization potentials for the multiply charged ions with acceptable computational time, since there is no need to optimize the exchange parameters.
