RELATIVISTIC DISTORTED-WAVE COLLISION STRENGTHS AND OSCILLATOR-STRENGTHS FOR F-LIKE IONS WITH 22-LESS-THAN-OR-EQUAL-TO-Z-LESS-THAN-OR-EQUAL-TO-92

Relativistic distorted-wave collision strengths have been calculated for the three transitions among the three levels with a hole in the n = 2 shell and for the 327 transitions from these levels to the excited levels with two holes in the n = 2 shell and one electron in the n = 3 shell in all the 71 F-like ions with nuclear charge number Z in the range 22 ≤ Z ≤ 92. The results are given here for a sample of 18 values of Z. 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 Zeff2 rydbergs with Zeff = Z - 6.667. In addition, the transition energies and electric dipole oscillator strengths are given. To our knowledge the present work is the first comprehensive publication of the results of fully relativistic calculations of the collision strengths for excitation of F-like ions. © 1991.
