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 3 s 3 p 4 , 3 s 2 3 p 2 3 d , 3 p 4 3 d , 3 s 3 p 2 3 d 2 configurations and for the 124 lowest states of the odd 3 s 2 3 p 3 , 3 p 5 , 3 s 3 p 3 3 d , 3 s 2 3 p 3 d 2 , 3 p 3 3 d 2 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 GRASP 2018.
