Abstract

Modern experimental techniques, including LIF lifetime and FTS branching fraction measurements, have increased the reliability of atomic transition probabilities in the UV and visible. However, this combination is problematic in the increasingly important IR region, resulting in a significant gap between the capabilities to record new astronomical spectra and the data needed to sufficiently analyze them. To aid in closing this gap, we are incorporating alternative techniques to measure sets of Fe-group oscillator strengths in the near-IR.
