Journal ArticleDOI
A hitherto unrecognized source of low-energy electrons in water
Melanie Mucke,Markus Braune,Silko Barth,Marko Förstel,Toralf Lischke,Volker Ulrich,Tiberiu Arion,Uwe Becker,Alexander M. Bradshaw,Uwe Hergenhahn +9 more
TL;DR: In this article, the authors investigate the production of low-energy electrons in amorphous medium-sized water clusters, which simulate water molecules in an aqueous environment, and identify a hitherto unrecognized extra source of lowenergy electrons produced by a non-local autoionization process called intermolecular coulombic decay (ICD).
Journal ArticleDOI
Autoionization Mediated by Electron Transfer
TL;DR: Electron-electron coincidence spectra of Ar-Kr clusters after photoionization have been measured and an electron with the kinetic energy range from 0 to approximately 1 eV is found in coincidence with the Ar 3s cluster photoelectron.
Journal ArticleDOI
Performance of a short 'magnetic bottle' electron spectrometer
Melanie Mucke,Marko Förstel,Toralf Lischke,Tiberiu Arion,Alexander M. Bradshaw,Uwe Hergenhahn +5 more
TL;DR: A newly constructed electron spectrometer of the magnetic bottle type is described, part of an apparatus for measuring the electron spectra of free clusters using synchrotron radiation, and results from testing the alignment of the magnet are discussed.
Journal ArticleDOI
Competition between proton transfer and intermolecular Coulombic decay in water
Clemens Richter,Daniel Hollas,Clara-Magdalena Saak,Marko Förstel,Tsveta Miteva,Melanie Mucke,Olle Björneholm,Nicolas Sisourat,Petr Slavíček,Uwe Hergenhahn,Uwe Hergenhahn +10 more
TL;DR: The authors use electron–electron coincidence detection to find the competitive roles of proton transfer and ICD that occur on similar time scales in water clusters and infer an intrinsic ICD lifetime of 12–52 fs for small water clusters.
Journal ArticleDOI
Observation of electronic energy bands in argon clusters
Marko Förstel,Melanie Mucke,Tiberiu Arion,Toralf Lischke,Silko Barth,Volker Ulrich,Gunnar Öhrwall,O. Björneholm,Uwe Hergenhahn,Alexander M. Bradshaw +9 more
TL;DR: In this paper, the 3p valence region of argon clusters was investigated with photoemission near the photoionization threshold, and a strong feature between 14.6 and 15.3 eV binding energy showed a photon-energy dependence indicative of electronic-energy band dispersion.
