Abstract

New wavelength measurements in the region from 950 to 12 000 Å were combined with the infrared data of Humphreys and Paul [ J. Opt. Soc. Am. 49, 1180 ( 1959)] to extend the analysis of Cl i. Electrodeless discharge lamps containing SiCl4, GeCl4, PbCl2, or chlorine gas were used to obtain wavelengths for 920 lines, of which 330 are interferometric values. The number of classified and observed lines has increased from about 550 and 780, to 1097 and 1173, respectively. Forty-three new even levels and 39 new odd levels were established, five levels were rejected, and some J values and configuration assignments were changed. The total number of known levels now stands at 112 odd and 128 even. The 3s3p6S2012 was found at 85 679 cm−1, and new levels belonging to each of the Cl ii 3p4 limit levels were established. Most of the new levels belong to the 3p4 6p, 3p 4nf n=6 to 8, 3p 4ns n=6 to 8, and 3p 4nd n=4 to 8 configurations. The improved measurements and energy level values lead us to propose 108 vuv lines with uncertainties of less than 0.0015 Å as reference wavelengths. The accuracy of the series limit corresponding to Cl ii 3p4 3P2 was improved slightly; the newly calculated value is 104591.0±0.3 cm−1.
