Energy and transition data computations for P-like ions: As, Kr, Sr, Zr, Mo, and W

Abstract

The multiconfiguration Dirac–Hartree–Fock (MCDHF) and relativistic configuration interaction (RCI) methods were used to compute excitation energies and transition data for the 147 lowest states of the even 3s3p4, 3s23p23d, 3p43d, 3s3p23d2 configurations and for the 124 lowest states of the odd 3s23p3, 3p5, 3s3p33d, 3s23p3d2, 3p33d2 configurations for the P-like ions: As XIX, Kr XXII, Sr XXIV, Zr XXVI, Mo XXVIII, and W LX. E1 transition rates and weighted oscillator strengths among these states are given. Valence–valence, core–valence and core–core electron correlation effects are included. Computed excitation energies and transition data are compared with the NIST recommended values and experimental or theoretical results of other authors. All calculations were performed using the general relativistic atomic structure package GRASP2018.
