Title: Electron impact collision strengths and oscillator strengths for Ge-, Ga-, Zn-, Cu-, Ni-, and Co-like Au ions

Abstract

Energy levels, oscillator strengths, and electron impact collision strengths have been calculated for Ge-, Ga-, Zn-, Cu-, Ni-, and Co-like Au ions. For Ni-like Au, these atomic data are obtained among the levels belonging to the configurations of ([Ne])3s{sup 2}3p{sup 6}3d{sup 10}, 3s{sup 2}3p{sup 6}3d{sup 9}nl, 3s{sup 2}3p{sup 5}3d{sup 10}nl, and 3s 3p{sup 6}3d{sup 10}nl (n=4, 5; l=0,1,...,n-1). For other Au ions, more levels have been obtained with special attention to atomic data up to transitions of 5f->3d for emission or 3d->5f for absorption. Configuration interactions are taken into account for all levels included. Collision strengths have been obtained at 20 scattered electron energies (5-40,000eV) and they are listed at six representative energies of 100, 500, 1000, 5000, 10,000, and 20,000eV in this work. Effective collision strengths have been obtained by assuming a Maxwellian electron velocity distribution at 10 representative temperatures ranging from 500 to 5000eV. The present dataset should be adequate for most applications. The energy levels are expected to be accurate to within 0.5%, while oscillator strengths and collision strengths for strong transitions are probably accurate to better than 20%. The complete dataset is available electronically from http://www.astronomy.csdb.cn/EIE/.

  • Wavelengths, transition probabilities, and oscillator strengths have been calculated for M-shell electric dipole transitions in Co-, Ni-, Cu-, Zn-, Ga-, Ge-, and Se-like Au ions. The fully relativistic multiconfiguration Dirac–Fock method, taking quantum electrodynamical effects and the Breit correction into account, was used in the calculations. Calculated energy levels of M-shell excited states for Cu-, Zn-, Ga-, Ge-, and Se-like Au ions from the method were compared with available theoretical and experimental results, and good agreement with them was achieved.
  • Energy levels, oscillator strengths, and electron impact collision strengths have been calculated for Ni-like ions of Nd (Z=60), Sm (Z=62), Eu (Z=63), Gd (Z=64), Ta (Z=73), and W (Z=74) among the 249 levels belonging to the ([Ne])3s{sup 2}3p{sup 6}3d{sup 10}, 3s{sup 2}3p{sup 6}3d{sup 9}nl, 3s{sup 2}3p{sup 5}3d{sup 10}nl, 3s3p{sup 6}3d{sup 10}nl (n=4, 5; l=0,1,...,n-1) configurations. Configuration interactions among these configurations have been included in the calculations. Collision strengths have been obtained at 20 scattered electron energies (5-20,000eV) and they have been listed at six representative energies of 100, 400, 1000, 2500, 5000, and 10,000eV in this work. Effective collision strengthsmore » have been obtained by assuming a Maxwellian electron velocity distribution at 24 temperatures ranging from 100 to 3000eV. Our results are compared with those available in the literature. The relative difference is within 0.3% between our calculated energy levels and the corresponding experimental values wherever available. The energy levels are expected to be be accurate within 0.6%, while oscillator strengths and collision strengths for strong transitions are probably accurate to better than 20%.

  • The primary objective of the calculations presented here is to provide reliable oscillator strengths for the analysis of solar spectra of Fe VIII and Ni X belonging to the 3s{sup 2}3p{sup 6}3d-3s{sup 2}3p{sup 5}3d{sup 2} transition array. To achieve this it was necessary to study interacting configurations which cross the 3s{sup 2}3p{sup 5}3d{sup 2} configuration for ions in the period between vanadium and copper and to compensate for inner-shell interactions. This study therefore yields atomic data for spectral lines of V V, Cr VI, Mn VII, Fe VIII, Co IX, Ni X, and Cu XI. The tabulated data consist ofmore » weighted oscillator strengths and calculated wavelengths for lines belonging to the 3s{sup 2}3p{sup 6}3d-3s{sup 2}3p{sup 5}3d{sup 2}, 3s{sup 2}3p{sup 6}3d-3s{sup 2}3p{sup 6}3d-3s{sup 2}3p{sup 6}4f, 5f, 6f, 7f, and 3s{sup 2}3p{sup 6}3d-3s{sup 2}3p{sup 5}3d4s transition arrays in V V through Cu XI and for some additional arrays in V V and Cr VI. Energy levels and their compositions are also listed as well as wavelengths derived from measured energy levels. For the calculations, Slater parameters are optimized on the basis of minimizing the discrepancies between observed and computed wavelengths. Configuration interaction was included between the 3s{sup 2}3p{sup 6}3d, 3s{sup 2}3p{sup 6}4d, 3s{sup 2}3p{sup 6}5d, 3s{sup 2}3p{sup 6}4s, 3s{sup 2}3p{sup 6}5s, and 3s{sup 2}3p{sup 5}3d4p even configurations and the 3s{sup 2}3p{sup 5}3d{sup 2}, 3s{sup 2}3p{sup 6}4p, 3s{sup 2}3p{sup 6}5p, 3s{sup 2}3p{sup 6}4f, 3s{sup 2}3p{sup 6}5f, 3s{sup 2}3p{sup 6}6f, 3s{sup 2}3p{sup 6}7f, 3s{sup 2}3p{sup 5}3d4s, and 3s{sup 2}3p{sup 5}3d4d odd configurations.« less
  • Energy levels, line strengths, oscillator strengths, radiative decay rates, and fine-structure collision strengths are presented for the Zn-like ions Nb XII and Mo XIII. The atomic data are calculated with the AUTOSTRUCTURE code, where relativistic corrections are introduced according to the Breit–Pauli distorted wave approach. We present the calculations of atomic data for 110 fine-structure levels generated from fifteen configurations (1s{sup 2}2s{sup 2}2p{sup 6}3s{sup 2}3p{sup 6}3d{sup 10})4s{sup 2}, 4s4p, 4p{sup 2}, 4s4d, 4s4f, 4s5s, 4p4d, 4s5p, 4s5d, 4p4f, 4p5s, 4d{sup 2}, 4d4f, 4f{sup 2}, and 3d{sup 9}4s{sup 2}4p. Fine-structure collision strengths for transitions from the ground and the first fourmore » excited levels are presented at six electron energies (20, 50, 80, 110, 150, and 180 Ryd). Our atomic structure data are compared with the available experimental and theoretical results.« less
  • Relativistic distorted-wave collision strengths have been calculated for the 105 {Delta}n = 0 transitions with n = 2 in the 81 N-like ions with nuclear charge number Z in the range 12 {le} Z {le} 92. The calculations were made for the six final, or scattered, electron energies E{prime} = 0.03, 0.08, 0.20, 0.42, 0.80, and 1.40, where E{prime} is in units of Z{sub eff}{sup 2} Ry with Z{sub eff} = Z {minus} 5. In addition, the transition energies and electric dipole oscillator strengths are given. To their knowledge the present work is the first comprehensive publication of the resultsmore » of fully relativistic calculations of the collision strengths for excitation of highly charged N-like ions.« less
