Abstract

Relative <i>A</i> values of 131 W I and 116 W II lines were measured in emission using a gas-driven shock tube as the spectroscopic source. Estimated accuracy of the relative data (3150–5600 Å) for each ionization stage is 6–50%. The ratio of ionic-to-neutral line strengths was determined within 30%. Wavelengths of 40 tungsten lines (3400–5300 Å) prominent in 1-eV plasmas, but not reported heretofore, were measured with typical reliability of ± 0.2 Å. Experimental W I line strengths are compared with data of Corliss and Bozman and trends of disagreement are examined.
