Charge Exchange Effects in Collisional Ionization Equilibrium of C,N, and O Ions [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2004
The charge exchange (or transfer) due to collision with hydrogen has important effects on the physical characteristics of astrophysical plasma.

Investigation of substituted-benzene dopants for charge exchange ionization of nonpolar compounds by atmospheric pressure photoionization [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2008
Atmospheric pressure photoionization (APPI) using a dopant enables both polar and nonpolar compounds to be analyzed by LC/MS. To date, the charge exchange ionization pathway utilized for nonpolar compounds has only been efficient under restrictive conditions, mainly because the usual charge exchange reagent ions--the dopant photoions themselves--tend ...

A Combined Desorption Ionization by Charge Exchange (DICE) and Desorption Electrospray Ionization (DESI) Source for Mass Spectrometry [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2011
A source that couples the desorption ionization by charge exchange (DICE) and desorption electrospray ionization (DESI) techniques together was demonstrated to broaden the range of compounds that can be analyzed in a single mass spectrometric experiment under ambient conditions. A tee union was used to mix the spray reagents into a partially immiscible

The role of charge-exchange processes in probing hydrogen plasma with a heavy ion beam

open access: yesMatter and Radiation at Extremes, 2023
Charge-changing processes of low-charged ions, used in hydrogen plasma probing by the heavy ion beam probe method, are considered. Along with the ionization of beam ions by plasma electrons and protons, the charge-exchange processes of ions on H atoms ...

Charge-Exchange Byproduct Cold Protons in the Earth’s Magnetosphere

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Owing to the spatial overlap of the ion plasma sheet (ring current) with the Earth’s neutral-hydrogen geocorona, there is a significant rate of occurrence of charge-exchange collisions in the dipolar portion of the Earth’s magnetosphere.

Charge exchange in fluid description of partially ionized plasmas [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
The effects of charge exchange on waves propagating in weakly ionized plasmas are discussed. It is shown that for low-frequency processes, ions and neutrals should be treated as a single fluid with some effective charge on all of them. We have derived a new momentum equation which should be used in such an environment.

Ion-acoustic waves in weakly ionized plasmas with charge-exchange collisions

open access: yesScientific Reports, 2023
AbstractIon-neutral charge-exchange collisions in plasmas of laboratory, space, and astrophysical origins are fundamental to understanding wave dissipation and wave generation phenomena. This paper implements a charge-exchange collision operator in the Boltzmann–Poisson system equations for a weakly ionized plasma.

Radial dependence of ionization losses of protons of the Earth's radiation belts [PDF]

open access: yesAnnales Geophysicae, 2016
Coulomb losses and charge exchange of protons are considered in detail. On the basis of modern models of the plasmasphere and the exosphere, the radial dependences of the rates of ionization losses of protons, with μ from 0.3 to 10 keV nT−1, of the ...
