Ionization of Hydrogen Atom by Proton Impact—How Accurate Is the Ionization Cross Section?
Atoms, 2023 For the control of fusion reactors, we need to accurately know all the possible reactions and collisional cross sections. Although large-scale trials have been performed over the last decades to obtain this data, many basic atomic and molecular cross ...

Hybrid CMP Slurry Supply System Using Ionization and Atomization
Applied Sciences, 2021 Chemical mechanical planarization (CMP) is frequently used in semiconductor manufacturing to polish the surfaces of multiple layers in a wafer. The CMP uses a slurry that aids in fabricating a smooth surface by removing the excess materials.

Dichroism Effects in the Ionization of Polarized Atoms by Short Circularly Polarized Laser Pulses
Photonics, 2023 The dichroism effects, i.e., asymmetries of the ionization probability with respect to the inversion of either the atomic orientation (magnetic dichroism, MD) or the circular polarization degree of the photon beam (circular dichroism, CD), are ...

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 ...
