Abstract

Transition probabilities for 2835 lines in Mo I between 2548 Å and 10565 Å have been measured by combining radiative level lifetimes, excited level populations measured in an inductively coupled plasma (ICP) source, and emission branching ratios measured with the ICP source and with a hollow cathode discharge source. We show that the level populations in the ICP source approximate a thermal distribution and use this property to interpolate between levels of known lifetime to find the population of levels of unknown lifetime. Comparison of the spectra from the two different sources distinguishes between Mo I and II lines and detects hidden blends and self-absorption in the hollow cathode source. Improved excitation energy for many Mo I levels was extracted from the high resolution Fourier transform spectrum, and 27 new levels were found.
