Measurement of the Relative Intensity of the Ly-(alpha) Lines in Fe 25+

Description

The intensity of the polarized Ly-α1 (2p3/2 → 1s1/2) transition has been measured relative to that of the unpolarized Ly-α2 (2p1/2 → 1s1/2) transition in Fe25+. The measurements were made with the Livermore electron beam ion trap EBIT-II for beam energies from threshold to 2.5 times threshold. The results are compared to the corresponding intensity ratio predicted using excitation cross sections from distorted-wave calculations, which includes polarization, the M1(2s1/2 → 1s1/2) transition, and cascade contributions. Discrepancies are found that tend to confirm a recent report of a measurement of the Ly-α lines in Ti21+ performed on the Tokyo electron beam ion trap
