Model-free pattern separation of two-color ultrafast X-ray diffraction
Linos Hecht, Yevheniy Ovcharenko, Asbjørn Ø. Lægdsmand +28
Two-color X-ray imaging with Free Electron Laser pulses offers a powerful approach for probing ultrafast structural dynamics in nanoscale systems, combining (near-)atomic spatial r…
Relaxation dynamics in excited helium nanodroplets probed with high resolution, time-resolved photoelectron spectroscopy
A. C. LaForge, J. D. Asmussen, B. Bastian +18
Superfluid helium nanodroplets are often considered as transparent and chemically inert nanometer-sized cryo-matrices for high-resolution or time-resolved spectroscopy of embedded…
Time-resolved imaging of an elusive molecular reaction: hydrogen roaming in acetonitrile
Debadarshini Mishra, Aaron C. LaForge, Lauren M. Gorman +3
Roaming has been proposed as a possible mechanism contributing to molecular dissociation in which the fragments can move around one another at relatively large intermolecular dista…
Diffraction imaging of light induced dynamics in xenon-doped helium nanodroplets
Bruno Langbehn, Yevheniy Ovcharenko, Andrew Clark +23
We have explored the light induced dynamics in superfluid helium nanodroplets with wide-angle scattering in a pump-probe measurement scheme. The droplets are doped with xenon atoms…
Time-resolved quantum beats in the fluorescence of helium resonantly excited by XUV radiation
AC LaForge, A Benediktovitch, V Sukharnikov +18
We report on the observation of time-resolved quantum beats in the helium fluorescence from the transition 1s3p -> 1s2s, where the initial state is excited by XUV free-electron las…
Resonance-enhanced multiphoton ionization in the x-ray regime
Aaron C. LaForge, Sang-Kil Son, Debadarshini Mishra +16
Here, we report on the nonlinear ionization of argon atoms in the short wavelength regime using ultraintense x rays from the European XFEL. After sequential multiphoton ionization,…
