RELATIVISTIC DISTORTED-WAVE COLLISION STRENGTHS AND OSCILLATOR-STRENGTHS FOR THE 71 NA-LIKE IONS WITH 22 LESS-THAN-OR-EQUAL-TO Z LESS-THAN-OR-EQUAL-TO 92

Relativistic distorted wave collision strengths are given for the 10 transitions among the 3s 1 2, 3p 1 2, 3p 3 2, and 3d 5 2 levels and for the 80 transitions from these levels to the excited levels nlj with n = 4 and 5 in the 71 Na-like ions with nuclear charge number Z in the range 22 ≤ Z ≤ 92. The calculations were made for the six final, or scattered, electron energies E′ = 0.0025, 0.015, 0.04, 0.10, 0.21, and 0.40, where E′ is in units of Zeff2 rydbergs with Zeff = Z - 8.34. 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 Na-like ions. © 1990.
