摘要：
The high-resolution measurements of Beiersdorfer et al. [Phys. Rev. A 100, 012511 (2019)] for the shifts of the 1s3p P-1(1) -> 1s(2) S-1(0) He-beta transition of Cl15+ are in significant disagreement with a generalized analytical approach calculations of Li and Rosmej [Europhys. Lett. 99, 33001 (2012)]. The multi-configuration Dirac-Fock method incorporating the average-atom ion-sphere model is applied to the problem. Our results are in good agreement with the experimental data across the full range of electron density measured. Oscillator strengths are also given. Systematic trends are observed for the properties under study regarding to increased temperature and electron density. (C) 2019 Elsevier Ltd. All rights reserved.
