Hyperfine Structure in the Neon Spectrum

Nature volume 119, page 237 (12 February 1927) | Download Citation



IN an investigation of the neon spectrum I have found that all lines, which arise from an s-term, have a component of shorter wave-length. The intensity of the satellite ranges from one-fourth to one-tenth that of the main line (according to a rough estimation). The separation of the components varies with the s-term concerned; for a 2s2 term it is 0.076 cm1; for a 2s3, term, 0.054 cm1; for a 2s4 term, 0.056 cm.1; and for a 2s5, term, 0 .058 cm.1. The structure is apparently due to a multiplicity in the s-levels. There are also evidences of a fine structure in the pd series lines, but complete resolution has not yet been attained.
