Abstract
FOR some time the spectrum of ionised argon (A II) has been a subject of investigation in the Amsterdam Laboratory ‘Physica.’ My analysis of the spectrum of neutral fluorine F I (Verslagen., Amsterdam, June 1926, Dec. 1926. Zeits. f. Phys., 39, 869; 1926) and the analysis of the spectrum of ionised neon Ne II (Versl., Amsterdam, May 1927. NATURE, 119, 925; 1927. Zeits. f. Phys., 44, 157; 1927. 46, 856; 1928) formed preliminary steps for the analysis of the A II spectrum. A great part of the A II lines have now been classified by me. I have found a doublet and a quartet term system. The term structure exhibits a perfect analogy to that of F I and Ne II. The following triplet 4p4S-4s4P: (9) 3729,300; (8) 3850,565; (7) 3928,599 involving the deep quartet 4s4P term with the term differences: 844,40 and 515,70, gives the key for the analysis of the spectrum. As examples, the other deep quartet terms are given:
