Negative ions of atoms and diatomic and triatomic molecules / Отрицательные ионы атомов, двухатомных и трехатомных молекул / Negativni joni atoma, dvoatomskih i troatomskih molekula

Vojnotehnički Glasnik, 2016
Electron affinity is not determined by solving the Schrödinger equation, but by using a wide range of various types of interactions. In atoms, the bound between the external electron and the integrated electric dipole moment of a neutral atom mainly ...

Kinetics of electrons and neutral particles in radio-frequency transformer coupled plasma H− ion source at Seoul National University

New Journal of Physics, 2016
In volume production H ^− ion sources, control of electron temperature is essential due to its close correlation with the generation of vibrationally-excited hydrogen molecules in the driver region as well as the generation of H ^− ions by dissociative ...

Development of negative muonium ion source for muon acceleration

Physical Review Accelerators and Beams, 2021
A negative muonium ion (Mu^{-}) source using an aluminum foil target (Al target) was developed as a low-energy muon source. Mu^{-} ions are produced by irradiating the Al target with a 3-MeV positive muon (μ^{+}) beam and observed using a microchannel ...

Negative Hydrogen and Deuterium Ion Density in a Low Pressure Plasma in Front of a Converter Surface at Different Work Functions

Plasma, 2021
Negative ion sources of neutral beam injection (NBI) systems for future fusion devices like ITER (“The Way” in Latin) rely on the surface conversion of hydrogen (or deuterium) atoms and positive ions to negative ions in an inductively coupled plasma (ICP)

Negative Ion Mode nanoLC-ESI-MS/MS Analyses of Permethylated Sulfated Glycans

Bio-Protocol, 2020
We have developed enabling techniques for sulfoglycomics based on MALDI-MS mapping and MS/MS sequencing of permethylated sulfated glycans. We then extended further the analytical workflow to C18 reverse phase (RP)-nanoLC-nanoESI-MS/MS analyses of ...
