Abstract
We have investigated the 2 2S1/2 - 4 2S1/2 two-photon transition in atomic lithium by high resolution laser spectroscopy. The frequencies of the two-photon resonances have been measured with an accuracy of better than 1 MHz using our Fabry-Perot wavemeter. The centers of gravity of the 4 2S1/2 levels are 35 012.033 582 (26) cm-1 for 7Li and 35 011.544 497 (30) cm-1 for 6Li. The transition isotope shift is 14 662.4 (10) MHz. We have also determined the magnetic hyperfine splitting constant for the 4 2S1/2 state for both isotopes.Citation
