Wavelengths and transition rates for $nl-n'l'$ transitions in Na-, Mg-, Al-, K-, Ca-, Zn-, Cd-, and Yb-like tungsten ions

POSTER

Abstract

Energies of levels with 1, 2, and 3 electrons above the closed shell in W ions are calculated. In particular, energies of Na- like ([Ne]$nl, n=3, 4$), Mg-like ([Ne]$3l3l'$), Al-like ([Ne]$3l3l'3l''$), K-like ([Ar]$nl, n=3, 4$), Ca-like ([Ar]$3d4l$), Zn-like ([Ni]$4l4l'$), Cd-like [Kr]$4d^{10}4f5l$), Yb-like ([Xe]$4f^{14}5l5l'$) tungsten are computed by relativistic many-body perturbation theory method (RMBPT code), the Multiconfiguration Relativistic Hebrew University Lawrence Atomic Code (HULLAC code), and the Hartree-Fock-Relativistic method (Cowan code). Wavelengths, transition rates, and line strengths are calculated for the dipole $nl-n'l'$ transitions in Na-, Mg-, Al-, K-, Ca-, Zn-, Cd-, and Yb-like tungsten ions. A detailed discussion of the various contributions to the dipole matrix elements and energy levels given by different codes is provided. These atomic data are important in modeling of M-, N-, and O- shell radiation spectra of heavy ions generated in various collision as well as plasma experiments. The tungsten data are particulary important for fusion application.
