Effects of the strong Breit interaction on the 2s2p–1s2s transitions of inner-shell hole states of helium-like ions
We have calculated the transition energies and probabilities of one-electron one-photon and two-electron one-photon transitions of middle-Z and high-Z He-like ions using the fully relativistic multi-configuration Dirac–Hartree–Fock method with active space method. The relativistic, electron correlation, Breit interaction and QED effects are systemically taken into account in the present work. The results demonstrate consistent agreement with both experimental and theoretical data, revealing notable inversion phenomena in the energy of one-electron one-photon transitions, particularly in double-hole states. Theoretical spectra intensities provide valuable insights into high-energy X-ray radiative processes from double-K-hole states.
