摘要

利用完全相对论多组态Dirac-Hartree-Fock方法和主动空间方法计算了中z和高z类he离子的单电子一光子和双电子一光子跃迁能量和概率。本文系统地考虑了相对论、电子相关、Breit相互作用和QED效应。结果与实验和理论数据一致,揭示了单电子单光子跃迁能量的显著反转现象,特别是在双空穴态。理论光谱强度提供了宝贵的见解高能x射线辐射过程从双k空穴状态。

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.
