Argon I Lines Produced in a Hollow Cathode Source, 332 nm to 5865 nm



W Whaling, W H. Anderson, M T. Carle, J W. Brault, H A. Zarem


We report precision measurements by Fourier transform spectroscopy of the vacuum wavenumber, line width, and relative signal strength of 927 lines in the AR I spectrum. Wavelength in air and classification of the transition are supplied for each line. A comparison of our results with other precision measurements illustrates the sensitivity of Ar I wavelengths to conditions in the light source.
