چکیده انگلیسی
Relativistic distorted-wave collision strengths have been calculated for the 16 În=0 optically allowed transitions with n=2 in the 67 O-like ions with nuclear charge number Z in the range 26â¤Zâ¤92. The calculations were made for the four final, or scattered, electron energies Eâ²=0.20,0.42,0.80, and 1.40, where Eâ² is in units of Zeff2 Ry with Zeff=Zâ5.83. In the present calculations, an improved “top-up” method, which employs relativistic plane waves, was used to obtain the high partial-wave contribution for each transition, in contrast to the partial-relativistic 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 O-like ions, but for a more comprehensive data set consisting of all possible 45 În=0 transitions, six scattered energies, and the 79 ions with Z in the range 14â¤Zâ¤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.
