Atomic data have received a great deal of attention, due to their need for the upcoming ITER project (International Thermonuclear Experimental Reactor). So, extensive spectroscopic studies both experimental and theoretical have been performed in the last years in order to estimate the power loss from the impurities in the forthcoming fusion reactors. Accurate values of wavelengths and their errors are required for interpretation of a wealth of high-resolution data obtained in the last two decades by the Chandra X-ray Observatory and the European Space Agency’s X-ray Multi-Mirror Mission .
As previously published [2, 3, 4, 5, 6, 7], we continue to focus on He-like ions. Energy levels, wavelengths, weighted oscillator strengths, transition probabilities and lifetimes are calculated for all levels of 1s2 and 1snl (n = 2−6) configurations of He-like cadmium ion.
The calculations were carried out using the GRASP2018 code based on the multiconfiguration Dirac-Hartree-Fock (MCDHF) . Transition probabilities are reported for all types of transitions (E1, E2, M1 and M2 transitions). Breit interactions and quantum electrodynamics effects are included in the RCI calculations. Comparisons were made with other data found in the literature and a good agreement was found which confirms the reliability of our results. We identified some new data that are calculated for the first time. This computational approach enables us to present a consistent and improved data set of all important transitions of the Cd XLVII spectrum, which are useful for identifying transition lines in further investigations.
