Hyperfine Structure of the Mercury Line 5471 A

Abstract

IN an attempt to explain the observed complicated structure of the mercury arc lines, Venkatesachar and Sibaiya^{1, 2} first suggested nuclear moments of ½ and 3/2 for the various isotopes of mercury. More recently, Schuler and Keystone³ in Germany and Murakawa⁴ in Japan have explained the structure of some prominent mercury are lines by ascribing a nuclear moment of ½ to the odd isotope with atomic weight 199 and 3/2 to that with 201.
