Abstract

An improved value of the 203Hg–198Hg isotope shift in the 2537 Å 3P11S0 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.

FIG. 1

Emission spectrum of the 2537 Å line made with the light source containing 203Hg. Sectoring was used to vary the exposure by successive factors of two as shown on the right of the spectrum. The position of the 203Hg F = 3 2 component, a, relative to 198Hg, given in units of 10−3 cm−1, is the result of all the measurements made in this work. The positions of the other 203Hg components are calculated from our precise level-crossing values of A and B (Ref. 12) and the measured position of the component a. The stable-mercury reference lines used are labelled 1, 3, and 4. The relative intensities of the hfs components for 203Hg are indicated on the energy-level diagram.

Absorption spectra of the 2537 Å line obtained with a cell containing 0.03% 203Hg in natural mercury. The applied magnetic fields, H, are indicated at the right of the two spectrograms. A zero-field emission spectrum from a 201Hg lamp, used for reference, was superimposed on each of the absorption spectra. Note that at the high field, the region of nearly total absorption by natural mercury is considerably extended.

Data points from measurements of 203Hg absorption spectra as a function of magnetic field for substates arising from 3P1, F = 3 2 level. The field-dependent and field-independent data are denoted by circles and triangles, respectively, and the superposed curves are the results of calculations. (See Sec. IC).

Vacuum manifold for fabrication of 203Hg light sources. The system is constructed from 10-mm-o.d. quartz and Pyrex tubing, except where noted otherwise. Residual gas pressure of ≈10−6 torr was obtained with an oil diffusion pump connected to the manifold through a liquid-nitrogen trap.

The results of measurements made with an applied magnetic field were reduceda to equivalent zero-field 203Hg ( F = 3 2 ) 198 Hg separations with the use of the values of the hfs interaction constants and of gJ obtained from Ref. 12. The quoted error limits for all of the separations, except as noted, represent statistical errors with a 95% confidence level.
