This situation has changed dramatically with the arrival of X-ray free-electron lasers: In the micro-focus of an X-ray free-electron laser, saturation of X-ray photoabsorption is routinely achieved. The immediate consequence is that the overall behavior of matter under such extreme conditions is characterized by efficient multiphoton absorption via a sequence of single-photon absorption events combined with inner-shell decay cascades and collisional ionization processes. In this way, unusual, highly excited states of matter are formed. Focusing on free atoms, this article provides a theoretical framework for the description of X-ray–matter interactions. The nature of X-ray multiphoton physics is explained, and the theory is compared with experimental data on atoms.}, cin = {FS-CFEL-3}, cid = {I:(DE-H253)FS-CFEL-3-20120731}, pnm = {6211 - Extreme States of Matter: From Cold Ions to Hot Plasmas (POF3-621)}, pid = {G:(DE-HGF)POF3-6211}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)7}, UT = {WOS:00}, doi = {10.1007/978-3-319-14394-1_25}, url = {https://bib-pubdb1.desy.de/record/301141}, }
