Ionization by electron impacts and ionization potential depression
Journal of Physics B: Atomic, Molecular and Optical Physics, 2022 Abstract We calculate the cross-section of ionization by free-electron impacts in high or moderate density plasmas. We show that the so-called ionization potential depression (IPD) strongly affects the magnitude of the cross-section in the high-density domain. We use the well-known IPD formulas of Stewart–Pyatt and Ecker–Kröll.

Ionization of acetonitrile [PDF]
International Journal of Mass Spectrometry, 2019 Abstract The ionization of acetonitrile has been studied using both electron and photon ionization combined with coincidence detection techniques. Relative partial ionization cross sections and relative precursor-specific partial ionization cross-sections are determined for all the cations formed from single, double and triple electron ionization of ...

Burns by Ionizing and Non-Ionizing Radiation [PDF]
Mediterranean Journal of Basic and Applied Sciences, 2021 This article consists of the study and investigative analysis of the effects of burns by radiation in humans. Cases of nuclear accidents, such as Chernobyl (ionizing radiation) and the effects of non-ionizing radiation such as infrared and microwave radiation are detailed.

Few Body Effects in the Electron and Positron Impact Ionization of Atoms
Atoms, 2021 Triple differential cross sections (TDCS) are presented for the electron and positron impact ionization of inert gas atoms in a range of energy sharing geometries where a number of significant few body effects compete to define the shape of the TDCS ...

Ionizing and Non-ionizing Radiation [PDF]
, 2020 This chapter describes ionizing radiation and non-ionizing radiation, ways to measure it in the environment, describes the potential health effects from chronic and acute exposures as well as a discussion addressing pregnancy concerns. Background radiation from both sources are described in relation to occupational or public exposure limits and how ...

Ionization behavior of nanoporous polyamide membranes
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Novel membrane processes and materials are needed to combat global water scarcity. The advancement of membrane materials for water purification processes such as desalination is hindered by our limited understanding of structure–property ...

Distortion of the Ionization Cross Section of He by the Coherence Properties of a C6+ Beam
Atoms, 2019 We analyze the influence of the coherence of the projectile’s beam in scattering phenomena. We focus our study in the ionization of He by C 6 + projectiles at 100 MeV/amu.
