Abstract

An analysis has been made of the discrepancies between the hfs and isotope shift results for Hg¹⁹⁴, Hg¹⁹⁵, and Hg^195m of Kleiman and Davis [ J. Opt. Soc. Am. 53, 822 ( 1963)] and our data, particularly in view of the importance of these results for our interpretation of the odd–even staggering effect in isotope shift [ W.J. T. III and H.H. S., Phys. Rev. Letters 8, 436 ( 1962)]. Our hfs results have been confirmed by the more precise level-crossing experiments of W. W. Smith [ Bull. Am. Phys. Soc. 8, 9 ( 1963)]. Errors in the work of Kleiman and Davis have been attributed, in part, to the presence of Hg¹⁹⁷ and Hg^197m in their sources. Experimental results are shown for the Hg¹⁹⁴ isotope shift. We find Hg¹⁹⁴ − Hg¹⁹⁶ isotope shift = 0.146 ± 0.010 cm⁻¹, and a preliminary value Hg^193m − Hg^195m shift = 0.150 cm⁻¹. These results lend further support to our hypothesis on the causes of odd–even staggering in isotope shift.
