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…
Interatomic Coulombic decay in lithium-doped large helium nanodroplets induced by photoelectron impact excitation
L. Ben Ltaief, K. Sishodia, J. D. Asmussen +5
Irradiation of condensed matter with ionizing radiation generally causes direct photoionization as well as secondary processes that often dominate the ionization dynamics. Here, la…
Fragmentation of Water Clusters Formed in Helium Nanodroplets by Charge Transfer and Penning Ionization
S. De, A. R. Abid, J. D. Asmussen +6
Helium nanodroplets ("HNDs") are widely used for forming tailor-made clusters and molecular complexes in a cold, transparent, and weakly-interacting matrix. Characterization of emb…
Observation of interatomic Coulombic decay induced by double excitation of helium in nanodroplets
B. Bastian, J. D. Asmussen, L. Ben Ltaief +9
Interatomic Coulombic decay (ICD) plays a crucial role in weakly bound complexes exposed to intense or high-energy radiation. So far, neutral or ionic atoms or molecules have been…
Spectroscopically resolved resonant interatomic Coulombic decay in photoexcited large He nanodroplets
L. Ben Ltaief, K. Sishodia, R. Richter +8
Interatomic Coulombic decay (ICD) processes play a crucial role in weakly bound complexes exposed to intense or high-energy radiation. Using large helium nanodroplets, we demonstra…
Secondary ionization of pyrimidine nucleobases and their microhydrated derivatives in helium nanodroplets
Jakob D. Asmussen, Abdul R. Abid, Akgash Sundaralingam +7
Radiation damage in biological systems by ionizing radiation is predominantly caused by secondary processes such as charge and energy transfer leading to the breaking of bonds in D…
Dopant ionization and efficiency of ion and electron ejection from helium nanodroplets
Jakob D. Asmussen, Ltaief Ben Ltaief, Keshav Sishodia +5
Photoionization spectroscopy and mass spectrometry of doped helium (He) nanodroplets rely on the ability to efficiently detect ions and/or electrons. Using a commercial quadrupole…
Electron energy loss and angular asymmetry induced by elastic scattering in helium droplets
Jakob D. Asmussen, Keshav Sishodia, Björn Bastian +10
Helium nanodroplets are ideal model systems to unravel the complex interaction of condensed matter with ionizing radiation. Here we study the effect of purely elastic electron scat…
A new endstation for extreme-ultraviolet spectroscopy of free clusters and nanodroplets
Björn Bastian, Jakob D. Asmussen, Ltaief Ben Ltaief +5
We present a new endstation for the AMOLine of the ASTRID2 synchrotron at Aarhus University, which combines a cluster and nanodroplet beam source with a velocity map imaging and ti…
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…
Time-resolved quantum beats in the fluorescence of helium resonantly excited by XUV radiation

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…
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…
