Abstract: 
We study two fundamental transitions from the ground state S-1(0) to P-1(1) (w line) and P-3(1) (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) = 13 114.47(14) eV and E(y) = 13 026.15(14) eV are in excellent agreement with quantum electrodynamics calculations, but disagree for w with the average of the hitherto reported experimental results (E) over bar (Lit)(w) = 13 115.15(17) eV. Independently of any energy calibration, we obtain a value E(w)/E(y) = 1.006 780(7), also in consistency with predictions.
