Revisiting CN− Formation Mechanisms in Electron Collisions with Benzonitrile
ChemPhysChem, EarlyView.This study explores negative ion formation via electron attachment, revealing CN− formation at 3.0 and 7–10 eV. Dissociation pathways are analyzed using G4(MP2) and CASPT2 calculations, highlighting the coupling between the π4* and σ* resonances critical for interstellar chemistry. Radiation‐induced processes in the aromatic cyano compound benzonitrile

ChemPlusChem, EarlyView.The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction
Contributions to Plasma Physics, EarlyView.ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Electron Density Structure Measurements With Scattered Intense Laser Beam
Contributions to Plasma Physics, EarlyView.ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.
