J/A+A/365/266  Fe XXIII fine structure level oscillator strengths (Tully+, 2001)

Oscillator strengths between fine structure levels of Fe XXIII. Tully J.A., Chidichimo M.C. <Astron. Astrophys. 365, 266 (2001)> =2001A&A...365..266T
ADC_Keywords: Atomic physics Keywords: Atomic data Abstract: We tabulate theoretical line strengths, f-values and transition energies for the beryllium-like ion Fe XXIII. Transitions are between levels 2l12l2S'L'J' and 2l3nl4SLJ with n = 2, 3, 4. The calculation uses the well known configuration interaction program CIV3 in which relativistic effects are allowed for by means of the Breit-Pauli approximation. We give a detailed comparison of our oscillator strengths with those which Chen & Ong (1998, Phys. Rev. A, 58, 1070) obtained using the relativistic Dirac code GRASP2. File Summary:
