摘要：

We present a study of the 1s2s 3S11s2p 3P0,2 transitions in Kr34+ and the 1s22s 2S1/21s22p 2P1/2,3/2 transitions in Kr33+. Wavelengths of two- and three-electron krypton ions have been accurately measured using the beam-foil technique. The limits of precision are discussed. Our results are compared with Z-expansion and multiconfigurational Dirac-Fock theories taking account of the two-electron quantum electrodynamics (QED) contributions we have calculated for high-Z ions. The agreement is satisfactory for heliumlike Kr35+. However, a sizable disagreement is found for the 2 P1/222p P3/22 fine structure of lithiumlike Kr36+, which could reflect the difficulty of calculating the QED corrections and retarded Breit interactions for three-electron ions. © 1990 The American Physical Society.
