Description

In the last few years, various theoretical and experimental research for providing atomic data for He-like ions have been carried out. For our calculations of atomic data for He-like oxygen, we have adopted the Multiconfigurational-Dirac-Hartree-Fock (MCDHF) method implemented in the General-Purpose Relativistic Atomic Structure Package (GRASP2K) code. Further relativistic corrections arising from the Breit interaction and QED effects have also been included. Additionally, in order to make a rigorous accuracy assessment of our results, we have also performed calculations by using the Many Body Perturbation Theory (MBPT) method implemented in the Flexible Atomic Code (FAC) of Gu.
The accuracy of the present calculations is high enough to facilitate identification of many observed spectral lines. There are required in the study of high-temperature plasmas such as those occurring in fusion energy research and in astrophysical research.
