Relativistic distortedwave collision strengths for the 16 Δn=0 optically allowed transitions with n=2 in the 67 Olike ions with 26≤Z≤92
Abstract
Relativistic distortedwave collision strengths have been calculated for the 16 Δn=0 optically allowed transitions with n=2 in the 67 Olike ions with nuclear charge number Z in the range 26≤Z≤92. The calculations were made for the four final, or scattered, electron energies E{sup ′}=0.20,0.42,0.80, and 1.40, where E{sup ′} is in units of Z{sub eff}{sup 2} Ry with Z{sub eff}=Z−5.83. In the present calculations, an improved “topup” method, which employs relativistic plane waves, was used to obtain the high partialwave contribution for each transition, in contrast to the partialrelativistic Coulomb–Bethe approximation used in previous work by Zhang and Sampson [H.L. Zhang, D.H. Sampson, At. Data Nucl. Data Tables 82 (2002) 357]. In that earlier work, collision strengths were also provided for Olike ions, but for a more comprehensive data set consisting of all possible 45 Δn=0 transitions, six scattered energies, and the 79 ions with Z in the range 14≤Z≤92. The collision strengths covered in the present work should be more accurate than the corresponding data given by Zhang and Sampson [H.L. Zhang, D.H. Sampson, At. Data Nucl. Data Tables 82 (2002) 357] and are presented here to replace those earlier results.

The calculations were made for the four final, or scattered, electron energies E{sup ′}=0.20, 0.42, 0.80, and 1.40, where E{sup ′} is in units of Z{sub eff}{sup 2} Ry with Z{sub eff}=Z−3.33.

Relativistic distortedwave collision strengths for the 49 Δn=0 optically allowed transitions with n=2 in the 67 Nlike ions with 26≤Z≤92
Relativistic distortedwave collision strengths have been calculated for the 49 Δn=0 optically allowed transitions with n=2 in the 67 Nlike ions with nuclear charge number Z in the range 26≤Z≤92. The calculations were made for the four final, or scattered, electron energies E{sup ′}=0.20, 0.42, 0.80, and 1.40, where E{sup ′} is in units of Z{sub eff}{sup 2} Ry with Z{sub eff}=Z−5. In the present calculations, an improved “topup” method, which employs relativistic plane waves, was used to obtain the high partialwave contribution for each transition, in contrast to the partialrelativistic Coulomb–Bethe approximation used in the previous work by Zhangmore » 
Relativistic distortedwave collision strengths for Δn = 0 transitions in the 67 Lilike, Flike and Nalike ions with 26 ≤ Z ≤ 92
We calculated relativistic distortedwave collision strength for all possible Δn=0 transitions, where n denotes the valence shell of the ground level, in the 67 Lilike, Flike and Nalike ions with Z in the range 26 ≤ Z ≤92. This choice produces 3 transitions with n=2 in the Lilike and Flike ions, and 10 transitions with n=3 in the Nalike ions. Moreover, for the Lilike and Flike ions, the calculations were made for the six final, or scattered, electron energies E'=0.008,0.04,0.10,0.21,0.41, and 0.75, where E' is in units of Zmore »
