Abstract

The hyperfine constants of krypton-81 and its isotope shifts relative to the stable krypton isotopes were measured for several transitions from the 5s [3/2] J = 2 metastable state. These measurements used continuous-wave single-frequency lasers for Doppler-free two-photon and saturated absorption spectroscopy. These measurements and the implications of the measured splittings for proposed ultratrace detection of krypton-81 for dating ancient ground water and glaciers will be discussed.
