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…
Extreme ultraviolet wave packet interferometry of the autoionizing HeNe dimer
Daniel Uhl, Andreas Wituschek, Rupert Michiels +24
Femtosecond extreme ultraviolet wave packet interferometry (XUV-WPI) was applied to study resonant inter-atomic Coulombic decay (ICD) in the HeNe dimer. The high demands on phase s…
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 Ultrafast Interatomic Coulombic Decay in Superexcited Sodium-doped Helium Nanodroplets
Jakob D. Asmussen, Rupert Michiels, Ulrich Bangert +16
The autoionization dynamics of superexcited superfluid He nanodroplets doped with Na atoms is studied by extreme-ultraviolet (XUV) time-resolved electron spectroscopy. Following ex…
Collective enhancement of above threshold ionization by resonantly excited helium nanodroplets
R. Michiels, M. Abu-samha, L. B. Madsen +18
Clusters and nanodroplets hold the promise of enhancing high-order nonlinear optical effects due to their high local density. However, only moderate enhancement has been demonstrat…
Unravelling the Full Relaxation Dynamics of Superexcited Helium Nanodroplets
Jakob D. Asmussen, Rupert Michiels, Katrin Dulitz +20
The relaxation dynamics of superexcited superfluid He nanodroplets is thoroughly investigated by means of extreme-ultraviolet (XUV) femtosecond electron and ion spectroscopy comple…
