【 摘 要 】
Synopsis We resolve the discrepancy between the existing theoretical oscillator strengths and the recent X-ray free electron laser (XFEL) experiment for the intensity ratio between two of the strongest emission lines from Ne-like Fe XVII (Fe16+) ion. Our study shows that, by considering the dynamic resonance induced population transfer between Fe XVII and Fe XVI (Fe15+) ions, which coexist in the XFEL experiment, we are able to successfully resolve this difference in theory and ex-periment. Further experimental works are suggested for a more detailed understanding of the dynamic resonance processes for ions under the plasma environment.
