“…With the measured absolute frequencies of A2 and B2 components, the absolute frequencies of A3 and B3 component are then derived from the A2-A3 and B2-B3 frequency intervals. Combining with the precise values of HFSs of 6P 3/2 [12] and 7S 1/2 [13], we are able to derive the center of gravity (c.g.) of the 6P 3/2 → 7S 1/2 transition frequency with an accuracy of 17 MHz.…”

“…Early literatures have reported precise HFS measurements with uncertainties <1 kHz for both 6P 1/2 and 6P 3/2 states using microwave magnetic resonance techniques in the 1950s [11,12]. Recently precise measurements of the absolute transition frequency and the HFS of the 6P 1/2 → 7S 1/2 transition have been reported [13]. However, no precise measurements have been carried out for the 6P 3/2 → 7S 1/2 transition at 535 nm up to now.…”

The saturated absorption spectrum of the 6P 3/2 → 7S 1/2 transition of 203 Tl and 205 Tl in a hollow cathode lamp has been observed with a frequency-doubled 1070 nm Nd : GdVO 4 laser. The third-derivative spectrum of the hyperfine components are obtained using the wavelength modulation spectroscopy and used to stabilize the laser frequency. The analysis of the error signal shows that the frequency stability reaches 30 kHz at 1 s averaging time. Such a frequency-stabilized light source at 535 nm can be used for laser cooling of thallium and for investigating the parity non-conservation effect in thallium. The absolute frequencies of hyperfine components are measured with an accuracy of 30 MHz using a precision wavelength meter. Including the pressure shift correction, the center of gravity of the transition frequency is determined to an accuracy of 22 MHz for both isotopes. Meanwhile, the isotope shift derived is in good agreement with earlier measurement.

“…On the other hand, we cannot a priori neglect the RHFA in the 2 D 3/2 state only in view of its leading 5d 9 6s 2 configuration without an unpaired s electron. For example, in thallium the RHFA value in the 6p P 3/2 state without an unpaired s electron in the leading configuration proves to be 5 times larger than that for the 7s S 1/2 state [36,56] due to the configuration mixing (see also the unexpectedly large RHFA for the 6p 3 4 S 3/2 state in bismuth [19]). The coincidence of the recalculated μ values with that from Ref.…”

The influence of the nuclear magnetization distribution effects on the hyperfine structure of electronic states of thallium atom is studied within the relativistic coupled cluster theory. Relative significance of these effects is demonstrated for the first excited electronic state 6P3/2 of neutral Tl. Based on the obtained theoretical and available experimental data, the nuclear magnetic moments of short-lived 191Tlm and 193Tlm isotopes are predicted: μ191 = 3.79(2) μN and μ193 = 3.84(3) μN, respectively. Using theoretical and experimental data for the neutral Tl, the magnetic anomalies 205Δ203 for the 7S1/2 state of the neutral Tl atom and the 1S1/2 state of the hydrogen-like ion are also predicted.
