Abstract

We study two fundamental transitions from the ground state ¹S₀ to ¹P₁ (w line) and ³P₁ (y line) in heliumlike Kr³⁴⁺ by resonant single-photon excitation using an electron-beam ion trap and monochromatic x rays at PETRA III. Our results for the transition energies E(w) = 13114.47(14) eV and E(y) = 13026.15(14) eV are in excellent agreement with quantum electrodynamics calculations, but disagree for w with the average of the hitherto reported experimental results Ē_Lit(w) = 13115.15(17) eV. Independently of any energy calibration, we obtain a value E(w)/E(y) = 1.006780(7), also in consistency with predictions.
