Abstract
Isotope shifts and hyperfine constants are reported for the radioactive isotopes and and the stable isotope . The previously unreported nuclear moments of were determined to be =-0.909(4) nuclear magneton and Q=+0.630(13) b from the hyperfine constants. This work increases the number of transitions for which hyperfine constants and isotope shifts have been measured from 1 to 4. The hyperfine anomaly for krypton reported in the previous measurement of hyperfine constants [H. Gerhardt et al., Hyperfine Interact. 9, 175 (1981)] is not supported by this work. The isotope shifts and hyperfine constants of measured in this work are in excellent agreement with previous work. Saturation spectroscopy was used to study transitions from krypton's metastable state to the , , and states. In saturation spectra, different line shapes were observed for the even- and odd-mass krypton isotopes. This even- versus odd-line-mass shape difference can be explained using the large cross section that has been reported for collisional transfer of the state excitation between krypton atoms. Two-color two-photon laser-induced fluorescence was used to measure the hyperfine spectra of the - transition using the state as the intermediate state. This technique proved to be more sensitive than saturation spectroscopy.
