论文摘要
我们回顾了有关天体物理兴趣原子离子的光离子化的最新研究，该研究已在Photon-Ion合并束设置管道上进行，这是Petraiii Synchrotron辐射源的Xuv Beam线P04永久安装的端站P04，由Desy在德国汉堡在德国汉堡运营。我们在天体物理环境中讨论了Fe+，Fe2+和Fe3+离子以及C-，C+，C4+，NE+和SI2+离子的单个和多个L壳光电离的结果。此外，这些实验结果证明了这一事实，即在世界上最明亮的同步加速器的光源之一上实施光子离子合并的梁法，这导致了与离子对原子内部壳光离子化过程的实验研究的突破。
We review recent work on the photoionization of atomic ions of astrophysical interest that has been carried out at the photon-ion merged-beams setup PIPE, a permanently installed end station at the XUV beamline P04 of the PETRAIII synchrotron radiation source operated by DESY in Hamburg, Germany. Our results on single and multiple L-shell photoionization of Fe+, Fe2+, and Fe3+ ions and on single and multiple K-shell photoionization of C-, C+, C4+, Ne+, and Si2+ ions are discussed in astrophysical contexts. Moreover, these experimental results bear witness of the fact, that the implementation of the photon-ion merged-beams method at one of the world's brightest synchrotron light sources has led to a breakthrough for the experimental study of atomic inner-shell photoionization processes with ions.
