Emergence of pseudoresonance in high-intensity resonant inelastic x-ray scattering Open
We report resonant inelastic x-ray scattering (RIXS) spectra of neon atoms interacting with intense x-ray pulses generated using an x-ray free-electron laser (XFEL). We find that an unexpected peak emerges near the K α line of Ne, whic…

Revisiting CN<sup>−</sup> Formation Mechanisms in Electron Collisions with Benzonitrile Open
Radiation‐induced processes in the aromatic cyano compound benzonitrile have attracted renewed interest since its detection in the interstellar medium in 2018, and recent studies have elucidated dissociative ionization pathways leading to …

Core-valence double ionization of carbon suboxide Open
We have measured the core-valence double ionization spectra of carbon suboxide above both the O 1s and C 1s edges. The spectra are compared with the well-known single ionization valence photoelectron spectrum of this system, from which the…

Sequential dissociation of ionized benzonitrile: New pathways to reactive interstellar ions and neutrals Open
Since benzonitrile’s discovery in the interstellar medium (ISM) in 2018, several studies have explored the strongest unimolecular dissociations of its radical cation (C 6 H 5 CN •+ ). However, sequential dissociation processes, which becom…

A Blyholder mechanism in the chemisorption of N2O on Ni(111) – studied with Auger-photoelectron coincidence spectroscopy Open
In heterogeneous catalysis the surface-adsorbate bond strength is critical for the function of the system. Here we study a series consisting of multilayer, bilayer and monolayer N2O on Ni(111) and employ Auger-photoelectron coincidence spe…

Resonant Auger spectroscopy on solid xenon on gold, silver, and copper substrates Open
An investigation of the radiationless decay of core excited Xe atoms in the region of Xe L3M4,5M4,5 Auger electron kinetic energies (using x-ray energies in the vicinity of the L3 threshold) is presented for Xe adsorbed on Cu, Ag, and Au. …

Electron ionization induced fragmentation pathways of trichloroanisole Open
This work probes electron-driven ionization of TCA. New fragment ions are identified by mass spectrometry and experimental appearance energies show excellent agreement with calculated threshold energies for the most significant pathways.

Boroxine benzaldehyde complex for pharmaceutical applications probed by electron interactions Open
Rationale 2,4,6‐Tris(4‐formylphenyl)boroxine (TFPB) is a substituted boroxine containing a benzaldehyde molecule bonded to each boron atom. Boroxine cages are an emerging class of functional nanostructures used in host–guest chemistry, and…

Low energy electron interactions with resveratrol and resorcinol: anion states and likely dissociation pathways Open
We report a computational study of the anion states of the resveratrol (RV) and resorcinol (RS) molecules, also investigating dissociative electron attachment (DEA) pathways. RV has well known beneficial effects in human health, and its an…

Halogen loss induced by electron collisions in halouracils at low energies Open
Synopsis We employed both eletronic scattering techniques and ab initio quantum dynamics to study electron-driven reactions in halouracils at low energies. Particularly, it was addressed halogen dissociation and H-loss probabilities in ani…

Transient anion spectra of the potential radiosensitizers 5-cyanateuracil and 5-thiocyanateuracil Open
We report on the low energy anion spectra of 5-cyanateuracil (5-OCNU) and 5-thiocyanateouracil (5-SCNU), which have been the suggested potential radiosensitizers for use in cancer therapy [L. Chomicz et al., J. Phys. Chem. Lett. 4, 2853–28…
