介绍了用来自同步辐射光源的X射线对质量/电荷选择的电离原子、分子和团簇进行光致电离的光子-离子合并束技术。从简单的少数电子系统的外层电离到复杂的多电子离子的内层电离，讨论了原子离子的光致电离的例子。阐明了基本的电离机制，指出了这些结果在天体物理和等离子体物理中应用的重要性。最后，以面内富勒烯离子为例，展示了光子-离子合束技术在研究纳米粒子光吸收方面的独特能力。
The photon-ion merged-beams technique for the photoionisation of mass/charge selected ionised atoms, molecules and clusters by x-rays from synchrotron radiation sources is introduced. Examples for photoionisation of atomic ions are discussed by going from outer shell ionisation of simple few electron systems to inner shell ionisation of complex many electron ions. Fundamental ionisation mechanisms are elucidated and the importance of the results for applications in astrophysics and plasma physics is pointed out. Finally, the unique capabilities of the photon-ion merged-beams technique for the study of photoabsorption by nanoparticles are demonstrated by the example of endohedral fullerene ions.
