Abstract

Using separated isotopes of tellurium, the hyperfine structure of the Te I and Te II spectra was studied. The magnetic moments of the two odd isotopes were calculated to be $μ ({Te}^{125}) = - 0.6 \pm 0.2$ nm, $μ ({Te}^{123}) = - 0.5 \pm 0.2$ nm. The ratio of the magnetic moments was determined to be $\frac{μ^{125}}{μ^{123}} = 1.186 \pm 0.007$ . Anomalous shift of the even isotopes was detected in the lines $λ 4006 (5 s 5 p^{4} {}^{4}P_{\frac{5}{2}} - 5 p^{2} ({}^{3}P_{0}) 6 p_{\frac{3}{2}})$ and $λ 4049 (5 s 5 p^{4} {}^{4}P_{\frac{3}{2}} - {[5 p^{2} ({}^{3}P_{1}) 6 p]}_{\frac{3}{2}})$ . The spacings between consecutive even isotopes in the line $λ 4006$ were as follows: $Δ (130 - 128) = 0.014$ , $Δ (128 - 126) = 0.011$ , $Δ (126 - 124) = 0.026$ , $Δ (124 - 122) = 0.017$ , $Δ (122 - 120) = 0.017$ ${cm}^{- 1}$ , the component due to the heaviest isotope lying on the largest frequency side. The centers of gravity of the odd isotopes in the line $λ 4006$ were: $Δ (124 - 125) = 0.002$ , $Δ (123 - 122) = 0.000$ ${cm}^{- 1}$ . $λ 4049$ showed nearly the same isotope effect as $λ 4006$ . Regarding the $μ$ values, see the note §.
