Low-energy cosmic rays (up to the GeV energy domain) play a crucial role in the physics
and chemistry of the densest phase of the interstellar medium. Unlike interstellar ionising …

Integral cross sections for optically allowed electronic-state excitations of atoms and
molecules by electron impact, by applying scaled plane-wave Born models, are reviewed …

Smilei is a collaborative, open-source, object-oriented (C++) particle-in-cell code. To benefit
from the latest advances in high-performance computing (HPC), Smilei is co-developed by …

The visualization of single-molecule reactions provides crucial insights into chemical
processes, and the ability to do so has grown with the advances in high-resolution …

Context. Galactic cosmic rays (CRs) are a ubiquitous source of ionisation of the interstellar
gas, competing with UV and X-ray photons as well as natural radioactivity in determining the …

In the present paper, we demonstrate that the exponential expansion of streamers
propagating in fields higher than the critical fields for stable propagation of streamers of a …

An analysis is presented of measured and calculated cross sections for inner-shell
ionization by electron impact. We describe the essentials of classical and semiclassical …

Total ionization cross sections of neutral carbon, nitrogen, and oxygen atoms by electron
impact are presented. In our theory we have included the possibilities that (a) some target …

Context. Low-energy cosmic rays (< 1 TeV) play a fundamental role in the chemical and
dynamical evolution of molecular clouds, as they control the ionisation, dissociation, and …

A method is described for computing total cross sections for the ionization of inner shells of
atoms and positive ions by impact of electrons and positrons with arbitrary energies. The …
