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…
Two-colour coherent control of nuclear and electron dynamics in photoionization of molecular hydrogen with FEL pulses
Fabian Holzmeier, Alberto Gonzalez-Castrillo, Thomas M. Baumann +12
The extension of coherent - control schemes, recently implemented in free-electron lasers (FELs), to molecular systems offers new opportunities to control chemical dynamic…
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…
Enhanced One-Color-Two-Photon Resonant Ionization in Highly Charged Ions by Fine-Structure Effects
Moto Togawa, Chunhai Lyu, Chintan Shah +25
Ultraintense pulses from X-ray free-electron lasers can drive, within femtoseconds, multiple processes in the inner shells of atoms and molecules in all phases of matter. The ensui…
