Rotational excitation of CH+ by electron impact [PDF]

, 1974
This is the published version, also available here: http://dx.doi.org/10.1103/PhysRevA.10.788.The cross sections for the rotational excitation of polar diatomic molecular ions by electron impact are formulated within the Coulomb-Born approximation.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Single-Electron Capture in Intermediate-Energy He⁺ + Ne Collisions

Atoms
State-selective single-electron capture in He+ + Ne collisions was studied at laboratory He+ projectile kinetic energies of 30–100 keV (corresponding to 7.5–25 keV/u) using a reaction microscope.

Comparative study of electron temperature in cascaded arc Ar/N2 plasma using laser Thomson scattering combined optical emission spectroscopy approach

AIP Advances, 2019
The expanding cascaded arc Ar/N2 plasma has been investigated by both the active and passive optical diagnostic technologies. In the investigation, the laser Thomson scattering (LTS) and optical emission spectroscopy (OES) have been adopted to measure ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Observation of O+ 4P-4D0 lines in proton aurora over Svalbard [PDF]

, 2004
Spectra of a proton aurora event show lines of O+ 4P-4D0 multiplet (4639–4696 Å) enhanced relative to the N2 +1N(0,2) compared to normal electron aurora. Conjugate satellite particle measurements are used as input to electron and proton transport models,

Plasmon Excitation in the Interaction of Slow Singly Charged Argon Ions with Magnesium

Solids
We report angle-resolved energy spectra of electron emitted in the interaction of slow singly charged heavy ions with Mg surface. The work is focused mainly on the excitation of plasmons of Mg under Argon impact.
