What is doublet discrimination? ABSTRACT This experiment aims to discern the wavelengths of the two sodium doublet lines1 by the use of a Michelson-interferometer, and then to discern the thickness of a sample of Mylar film utilising the same equipment. We get lower limits {l}_{1}\geqslant 2.1 cm for the D1 line and {l}_{2}\geqslant 2.7 cm for the D2 line. /Filter[/FlateDecode] In this paper we present the results of intensity measurements of D 1 (589.5224 nm) and D 2 (588.9950 nm) sodium doublet spectral lines emitted from a short-lifetime plasma randomly appearing across the aluminum anode surface during its electrolytic oxidation from the water solution of boric acid with sodium tetraborate. 500 500 611.1 500 277.8 833.3 750 833.3 416.7 666.7 666.7 777.8 777.8 444.4 444.4 3 Present address: SUPSI-DFA, Piazza S.
