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…
Long-lasting XUV activation of helium nanodroplets for avalanche ionization
C. Medina, A. Ø. Lægdsmand, L. Ben Ltaief +13
We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse. In…
