X-ray Driven Trihydrogen Formation on Silica Nanosurfaces
Samuel Sahel-Schackis, Adam Summers, Ritika Dagar +29
The trihydrogen cation () initiates the ion-molecule reactions that build molecular complexity in interstellar space. Whether its canonical formation reaction, $\ma…
Photoinduced enhancement of chemical shift sensitivity to local vibrations
Ana MartÃnez Gutiérrez, Oliver Alexander, Pablo Estévez Alonso +26
The advent of novel free-electron laser sources enabling time-resolved x-ray photoelectron spectroscopy (tr-XPS) provides a unique opportunity to monitor local chemical environment…
Attosecond soft X-ray pulses generated by chirp-dispersed manipulation in an XFEL reveal nonlinear core-electron dynamics in neon
Lars Funke, Markus Ilchen, Svitozar Serkez +59
Free-electron lasers have demonstrated their capability of generating intense attosecond X-ray pulses, which are the key to studying electron dynamics at their natural time scale a…
Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern
Linos Hecht, Andre Al Haddad, Björn Bastian +47
We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…
Probing the structure of cyclic hydrocarbon molecules with X-ray-induced Coulomb explosion imaging
Kurtis D. Borne, Rebecca Boll, Thomas M. Baumann +27
Coulomb explosion imaging (CEI) is a powerful experimental technique that maps a molecule's geometric structure onto the momenta of ionic molecular fragments produced by rapid mult…
Unraveling real-time chemical shifts in the ultrafast regime
Daniel E. Rivas, Lorenzo Paoloni, Rebecca Boll +21
Traditional x-ray photoelectron spectroscopy (XPS) relies upon a direct mapping between the photoelectron binding energies and the local chemical environment, which is well-charact…
