“…A number of lines have also been detected using beam-foil techniques in the wavelength region λ500-λ1000 Å (Pinnington et al 1971), theta pinch experiments (Hansen & Persson 1987) for the optical region, and also through capillary-discharge tube experiments (Luna et al 2000). A compilation of weighted oscillator strengths have been evaluated through a Multi-Configuration Hartree-Fock mchf approach in two separate cases (Luna et al 2001;Froese Fischer et al 2006).…”

Photoionization cross sections are obtained using the relativistic Dirac Atomic Rmatrix Codes (darc) for all valence and L-shell energy ranges between 27-270eV. A total of 557 levels arising from the dominant configurations 3s 2 3p 4 , 3s3p 5 , 3p 6 , 3s 2 3p 3 [3d, 4s, 4p], 3p 5 3d, 3s 2 3p 2 3d 2 , 3s3p 4 3d, 3s3p 3 3d 2 and 2s 2 2p 5 3s 2 3p 5 have been included in the target wavefunction representation of the Ar iii ion, including up to 4p in the orbital basis. We also performed a smaller Breit-Pauli (bp) calculation containing the lowest 124 levels. Direct comparisons are made with previous theoretical and experimental work for both valence shell and L-shell photoionization. Excellent agreement was found for transitions involving the 2 P o initial state to all allowed final states for both calculations across a range of photon energies. A number of resonant states have been identified to help analyze and explain the nature of the spectra at photon energies between 250 and 270eV.

The energy levels and observed spectral lines of ionized argon atoms, in all stages of ionization, have been compiled. Sufficient experimental data were found to generate level and line tables for ArII through ArXV. For ArXVI a mix of experimental and theoretical data were used. Because of the superiority of the theoretical data for ArXVII and ArXVIII, theoretical values are compiled for the energy levels and the lines are calculated from them. Experimental g-factors are included for ArII. A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.
