| Zusammenfassung | We report measurements of the transition frequencies 4s 2S1/2–4p 2P1/2 and 4s 2S1/2–4p 2P3/2 of the potassium isotopes 39, 40, and 41 through an atomic beam experiment with a fractional uncertainty of about 2×10–10. For frequency calibration, a fs-laser comb referenced to a Cs atomic clock was used. Compared to previous results, hyperfine constants for the states 4p 2P1/2 and 4p 2P3/2 and isotope shifts are given with a considerably reduced uncertainty. This paper also resolves the discrepancy of transition frequencies measured by Banerjee et al. [Phys. Rev. A 70, 052505 (2004)] and Scherf et al. [Z. Phys. D 36, 31 (1996)] and the hyperfine constant A(39K,2P1/2) reported by Banerjee et al. [Europhys. Lett. 65, 172 (2004)] and Bendali et al. [J. Phys. B 14, 4231 (1981)]. |
