Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method
Atoms, 2021 The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems.

The Atmospheric Influence on Cosmic-Ray-Induced Ionization and Absorbed Dose Rates
Universe, 2023 When high-energy particles originating from space penetrate the atmosphere, they may interact with atoms and molecules, initiating air showers composed of secondary and tertiary particles propagating towards the ground.

The ionization of the diffuse ionized gas
The Astrophysical Journal, 1994 The diffuse ionized gas (DIG), responsible for producing the faint but pervasive H(sub alpha), requires 15% of the power of all Galactic O stars for its ionization. No other source of ionization seems practical. The spectrum is strong in low stages of ionization (N II, SII), weak in (O III), and very weak in (O I) lambda 6300, at least in one well ...

Cavity-enhanced photoionization of an ultracold rubidium beam for application in focused ion beams [PDF]
, 2017 A two-step photoionization strategy of an ultracold rubidium beam for application in a focused ion beam instrument is analyzed and implemented. In this strategy the atomic beam is partly selected with an aperture after which the transmitted atoms are ...

The different origins of high- and low-ionization broad emission lines revealed by gravitational microlensing in the Einstein cross [PDF]
, 2016 We investigate the kinematics and ionization structure of the broad emission line region of the gravitationally lensed quasar QSO2237+0305 (the Einstein cross) using differential microlensing in the high- and low-ionization broad emission lines.
