Title: Oscillator strengths of neutral yttrium (Y I) from hook-method measurements in a furnace

Journal Article · · J. Opt. Soc. Am.; (United States)

Relative oscillator strengths for 33 neutral yttrium (Y I) transitions between 2723 and 4761 A have been measured by the hook method. The data have been analyzed and placed on an absolute scale by using a numerical procedure developed by Cardon, Smith, and Whaling and the published absolute lifetimes of Beer, and Andersen, Ramanujam, and Bahr. The z/sup 2/F/sup 0//sub 5/2/ level lifetime of Beer is found to be in error. The absolute lifetime of the level y/sup 2/P/sup 0//sub 3/2/ is determined to be 36 +- 4 ns. The total uncertainties in the absolute oscillator strengths are between 9% and 14%.
