Abstract

Vacuum ultraviolet Si I wavelengths have been recalculated using all available low-pressure-source data. One hundred calculated and forty-one measured wavelengths, all with uncertainties less than 0.002 Å, should be useful as wavelength standards in the region 1560 to 2000 Å. Seventy-seven of the proposed standards were originally calculated by Radziemski and Andrew [J. Opt. Soc. Am. <b>55</b>, 474 (1965)]; although the two sets of wavelength values agree to within their uncertainties, the new set has a greater internal consistency. Included also is a complete list of low-pressure-source levels for Si I, which contains new values for 30 odd levels previously determined exclusively from relatively high-pressure (450–740 torr) arc data.
