Abstract

An improved value of the 203Hg-198Hg isotope shift in the 2537 Å 3P1-1S0 line of mercury was determined from emission spectroscopy, with mass-separated samples, and from absorption spectroscopy with unenriched pile-produced isotope. The spectroscopic data were analyzed to yield the isotope shift by use of precise hfs interaction constants that we obtained previously from a level-crossing experiment. The new value for the 203Hg-198Hg isotope shift is IS(203-198) = 0.392 ± 0.006 cm-1; 203Hg lies at the lower-wave-number side. The experiment demonstrates the advantages of absorption spectroscopy for samples of low isotopic purity. The application of this technique to work with small samples is also discussed.
