Hyperfine splittings and isotope shifts in eight transitions from the metastable 4p5 5s J=2 and J=0 states of Kr I

We report isotope shifts for eight transitions in Kr I for all the stable isotopes and hyperfine constants for the 1s5, 2p9, 2p8, 2p7, 2p6, 2p4, 2p3, 3p9, and 4d4' states in 83Kr. We used continuous-wave single-frequency lasers to perform resonance ionization on an atomic beam of krypton atoms in the metastable 1s5 and 1s3 states of the 4p5 5s configuration. Our results agree well with previous work and with calculations of the hyperfine constants for 83Kr in the 4p5 5p states
