XUV fluorescence as a probe of interatomic Coulombic decay of resonantly excited He nanodroplets
Keshav Sishodia, Ltaief Ben Ltaief, Niklas Scheel +15
Superfluid He nanodroplets resonantly excited by extreme ultraviolet (XUV) pulses exhibit complex relaxation dynamics, including the formation of metastable excited He atoms tr…
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…
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…
Efficient Indirect Interatomic Coulombic Decay Induced by Photoelectron Impact Excitation in Large He Nanodroplets
L. Ben Ltaief, K. Sishodia, S. Mandal +7
Ionization of matter by energetic radiation generally causes complex secondary reactions which are hard to decipher. Using large helium nanodroplets irradiated by XUV photons, we s…
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…
Fourfold Differential Photoelectron Circular Dichroism
K. Fehre, N. M. Novikovskiy, S. Grundmann +28
We report on a joint experimental and theoretical study of photoelectron circular dichroism (PECD) in methyloxirane. By detecting O 1s-photoelectrons in coincidence with fragment i…
Photoelectron spectroscopy of coronene molecules embedded in helium nanodroplets
L. Ben Ltaief, M. Shcherbinin, S. Mandal +5
We present the first measurement of a one-photon extreme-ultraviolet photoelectron spectrum (PES) of molecules embedded in superfluid helium nanodroplets. The PES of coronene is co…
Charge-exchange dominates long-range interatomic Coulombic decay of excited metal-doped He nanodroplets
L. Ben Ltaief, M. Shcherbinin, S. Mandal +9
Atoms and molecules attached to rare gas clusters are ionized by an interatomic autoionization process traditionally termed 'Penning ionization' when the host cluster is resonantly…
