Solar UV and X-ray spectral diagnostics
Giulio Del Zanna,Helen E. Mason +1 more
TL;DR: In this article, a review of the diagnostic methods used to measure electron densities, electron temperatures, differential emission measure (DEM), and relative chemical abundances is presented, focusing on the optically thin emission from the solar atmosphere, mostly found at UV and X-ray (XUV) wavelengths.
Journal ArticleDOI
Migdal Effect in Dark Matter Direct Detection Experiments
TL;DR: In this paper, the authors reformulate the Migdal's approach so that the "atomic recoil" cross section is obtained coherently, where they make transparent the energy-momentum conservation and the probability conservation.

Binary-encounter-dipole model for electron-impact ionization
Yong-Ki Kim,M. Eugene Rudd +1 more
TL;DR: In this article, a theoretical model for calculating electron-impact ionization cross sections for atoms and molecules is presented, which combines the binary-encounter theory with the dipole interaction of the Bethe theory for fast incident electrons.

Techniques for the calculation of atomic structures and radiative data including relativistic corrections
TL;DR: Superstructure as mentioned in this paper is a general-purpose automatic atomic-structure program that uses multi-configuration type expansions to calculate term energies, intermediate-coupling energy levels, term coupling coefficients, and cascade coefficients.
Journal ArticleDOI
RMATRX1: Belfast atomic R-matrix codes
TL;DR: RMATRX1 as mentioned in this paper is a general program to calculate atomic continuum processes using the R -matrix method, including electronatom and electron-ion scattering, and radiative processes such as bound-bound transitions, photoionization and polarizabilities.
