Energy and Charge Transfer in Xenon Dimers and Trimers after XUV-photoionization at FLASH2 — •Hannes Lindenblatt1, Kirsten Schnorr2, Sven Augustin2, Severin Meister1, Florian Trost1, Patrizia Schoch1, Georg Schmid1, Yifan Liu1, Markus Braune3, Marion Kuhlmann3, Rolf Treusch3, Claus Dieter Schröter1, Thomas Pfeifer1, and Robert Moshammer11Max-Planck-Institut für Kernphysik, Heidelberg — 2Paul Scherrer Institut, Villigen, Schweiz — 3DESY, Hamburg

We investigated the relaxation dynamics of xenon dimers and trimers employing momentum coincidence spectroscopy at the reaction microscope beamline FL26 at FLASH2. Using the grazing incidence split, delay and focusing optics, an XUV-XUV pump-probe scheme was utilized to track dissociation dynamics. On the poster, we present the measurement scheme and time-resolved results for different fragmentation channels. For example, in dimer-fragmentation we identified the role of radiative electron-transfer, and for trimers the so-called electron transfer-mediated decay (ETMD3), where all three atoms are involved, was observed as function of time.

Keywords: Xenon oligomers; momentum coincidence spectroscopy; time-resolved XUV pump-probe; RCT; ETMD(3)
