Measurement of hyperfine structures and isotope shifts of the thallium 6/sup 2/P/sub 1/2/-7/sup 2/D/sub 3/2,5/2/ levels by using the saturated and linear absorption spectroscopy with velocity selective optical pumping

Kwang-Hoon Ko, Sang Eon Park, Do-Young Jeong +4 more

The linear and saturated absorption spectroscopy was performed for the 6/sup 2/P/sub 1/2/-7/sup 2/D/sub 3/2,5/2/ transition lines of /sup 203,205/Tl isotopes. The dependences of the cross-over and the isotope signals in saturated absorption spectra were measured and analyzed on the optical pumping power. The hyperfine splittings and isotope shifts of the 7/sup 2/D/sub 3/2,5/2/ levels of Tl atoms were also measured.

This line is of primary importance for laser-cooling applications. In addition, an experimental value of the field and specific mass shift coefficients of the transition is reported as well as the hyperfine structure magnetic dipole coupling constant $A$ of the transition excited state in $^{57}\text{Fe}$ , namely $A(3{d}^{7}4p\phantom{\rule{0.28em}{0ex}}z\phantom{\rule{0.28em}{0ex}}{}^{5}{G}_{6}^{o})=31.241(48)$ MHz. The measurements were carried out by means of laser-induced fluorescence spectroscopy performed on an isotope-enriched iron atomic beam. All measured frequency shifts are reported with relative uncertainties below one third percent.We report on the measurement of the isotope shifts of the $3{d}^{7}4s\phantom{\rule{0.28em}{0ex}}a\phantom{\rule{0.28em}{0ex}}{}^{5}{F}_{5}\text{--}3{d}^{7}4p\phantom{\rule{0.28em}{0ex}}z\phantom{\rule{0.28em}{0ex}}{}^{5}{G}_{6}^{o}$ Fe i line at 358 nm between all four stable isotopes $^{54}\text{Fe},\phantom{\rule{0.16em}{0ex}}^{56}\text{Fe},\phantom{\rule{0.16em}{0ex}}^{57}\text{Fe}$, and $^{58}\text{Fe}$, as well as the hyperfine structure of that line for $^{57}\text{Fe}$, the only stable isotope having a nonzero nuclear spin.
