Autoionization is an important pathway for the relaxation of electronically excited states. In
weakly bonded matter, efficient autoionization channels have been found, in which not only …

Purpose: The paper gives an introduction into Interatomic and Intermolecular Coulombic
Decay (ICD). ICD is an autoionization process, which contrary to Auger decay involves …

As a first step towards meeting the recent demand for new computational tools capable of
reproducing molecular-ionization continua in a wide energy range, we introduce a hybrid …

Coincidence spectroscopy is a powerful spectroscopic method addressing the recording of
more than one particle involved in an ionization process simultaneously. In the current …

Auger decay after photoexcitation or photoemission of an electron from a deep inner shell in
the hard X-ray regime can be rather complex, implying a multitude of phenomena such as …

Thermally driven chemistry as well as materials' functionality are determined by the potential
energy surface of a systems electronic ground state. This makes the potential energy surface …

When a core-shell electron is ionized by coherent ultrashort x-ray pulses with varied
duration, different nuclear wave packets of a cationic molecule are formed, which can be …

Observing and controlling molecular motion and in particular rotation are fundamental topics
in physics and chemistry. To initiate ultrafast rotation, one needs a way to transfer a large …

Spectra reflecting the formation of single-site double-core-hole pre-edge states involving the
N 1s and C 1s core levels of acetonitrile have been recorded by means of high-resolution …

Photoelectron–Auger electron coincidence spectroscopy probes the dicationic states
produced by Auger decay following the photoionization of core or inner valence levels in …
