Journal ArticleDOI
Size-Resolved Photoelectron Anisotropy of Gas Phase Water Clusters and Predictions for Liquid Water.
TL;DR: First measurements of size-resolved photoelectron angular distributions for the valence orbitals of neutral water clusters with up to 20 molecules are reported, suggesting the latter to be the result of a local short-range scattering potential that is fully described by a unit of 5-6 molecules.
Journal ArticleDOI
Low-energy constraints on photoelectron spectra measured from liquid water and aqueous solutions.

Neumark,Daniel M. Neumark,Gerard Meijer,Iain Wilkinson,Bernd Winter,Stephan Thürmer +24 more
TL;DR: In this article, the effects of electron collision and indirect ionization processes, occurring at photoexcitation and electron kinetic energies well below 30 eV, on the photoemission spectra of liquid water were investigated.
Journal ArticleDOI
Electron scattering in large water clusters from photoelectron imaging with high harmonic radiation
Thomas E. Gartmann,Sebastian Hartweg,Loren Ban,Egor Chasovskikh,Bruce L. Yoder,Ruth Signorell +5 more
TL;DR: Low-energy electron scattering in water clusters (H2O)n with average cluster sizes of n < 700 is investigated by angle-resolved photoelectron spectroscopy using high harmonic radiation at photon energies of 14.0, 20.3, and 26.5 eV for ionization from the three outermost valence orbitals.
Journal ArticleDOI
Stability of aerosol droplets in Bessel beam optical traps under constant and pulsed external forces.
Grégory David,Kıvanç Esat,Sebastian Hartweg,Johannes W. Cremer,Egor Chasovskikh,Ruth Signorell +5 more
TL;DR: Under the influence of a constant gas flow (constant external force), the QBB trap is found to be more stable compared with the CPBB trap, while under pulsed laser excitation with laser pulse durations of nanoseconds (pulsed external force) the type of trap is of minor importance for the droplet stability.
Journal ArticleDOI
Condensation Effects on Electron Chiral Asymmetries in the Photoionization of Serine: From Free Molecules to Nanoparticles
TL;DR: In this paper, angle-resolved valence photoelectron spectroscopy was used to investigate structural changes at the molecular level, occurring at the onset of condensation, which can be probed by angle-resolution valence spectrograms.
