Spectral properties of neutral selenium and tellurium. A relativistic treatment

Oscillator strengths for fine‐structure transitions in the complex atomic systems, neutral selenium, and tellurium, are reported. The calculations were carried out using the relativistic quantum defect orbital method. The resulting oscillator strengths are analyzed in terms of other theoretical and experimental data. In addition, to estimate the correctness of our oscillator strengths for these species, we have also analyzed the regularities complied by the calculated f ‐values. © 2001 John Wiley & Sons, Inc.
