Electron-impact ionization cross sections for all atomic ions in the W isonuclear sequence
are calculated using a variety of theoretical methods. For the direct ionization process, a …

We have investigated atomic ionization dynamics in Kr in the transition regime from
nonrelativistic to relativistic laser intensities (10 16 to 10 18 W/cm 2) by measuring yields of …

We have conducted a large-scale survey of 120 planetary nebulae (PNe) to search for the
near-infrared emission lines [Kr III] 2.199 μm and [Se IV] 2.287 μm. The neutron (n)-capture …

A femtosecond two-photon-absorption laser-induced-fluorescence (TALIF) diagnostic was
designed, installed, and operated on the Princeton-Field-Reversed Configuration-2 device …

Abstract Using the multiconfiguration Dirac–Fock method and the second–order many–body
perturbation theory method, highly accurate calculations are performed for the lowest 344 …

We present recent measurements of absolute electron-impact ionization cross sections for
Be-like C iii, N iv, and O v forming Li-like C iv, N v, and O vi. The measurements were taken …

An extensive spectroscopic investigation of Kr+ plasma has been carried out through a
comprehensive collisional-radiative plasma model along with the calculations of electron …

Absolute cross sections, σ q+, for multiple ionization of He (q= 1), Ne (q= 1, 2, and 3), Ar (q=
1, 2, 3, and 4), Kr (q= 1, 2, 3, and 4), and Xe (q= 1, 2, 3, 4, and 5) atoms by protons in the …

Electron-impact single ionization cross sections for W q+(q= 4–5) were calculated using the
flexible atomic code (FAC) in the level-to-level distorted-wave method, considering the …

A multi-institutional team of undergraduate students conducted an independent study in
which they designed, fabricated, and tested a small Hall effect thruster. The study was …
