TLDR
In this article, bound-bound and bound-free oscillator strengths are calculated based on a self-consistent Hartree-Fock-Slater model of the atom and the effect of variable matter density is analyzed in detail for cold helium.Abstract:
Bound-bound and bound-free oscillator strengths are calculated based on a self-consistent Hartree-Fock-Slater model of the atom. The effect of variable matter density is analyzed in detail for cold helium. Data are also presented for the Al13 and Cs55 atoms at different temperatures and matter densities.read more

Spectroscopy of Confined Atomic Systems: Effect of Plasma
TL;DR: In this article, the effect of spatial and other external confinements on the ground and excited state energy levels of many electron atoms, ions and exotic systems is discussed, and the spectral line shifts under strongly coupled plasma have been compared with data available from laser plasma experiments.

Hyperpolarizability of two electron atoms under spherically confined Debye plasma
TL;DR: In this paper, He, the first neutral member of the two electron sequence, has been performed under spherical confinement with a view to analyse the effect of pressure on such non linear optical properties.

Spectral lines in hot dense matter
TL;DR: In this article, an algorithm for the computation of photoabsorption cross sections at arbitrary temperature and matter density is presented for the beryllium and germanium plasmas in the frequency region of spectral lines.

Screening effects upon spectral lines in hot matter
TL;DR: In this paper, the Hartree-Fock-Slater average-atom model was used to calculate transition energies and oscillator strengths for the principal series of HeII and LiII in hot plasmas.

Quantum Mechanics of One- and Two-Electron Atoms
Hans A. Bethe,Edwin E. Salpeter +1 more
TL;DR: The theory of atoms with one or two electrons is the simplest and most completely treated field of application of quantum mechanics as mentioned in this paper, and it is one of the simplest fields of application for quantum mechanics.
The Theory of Atomic Spectra
Edward U. Condon,G. H. Shortley +1 more
TL;DR: In this paper, the quantum mechanical method is applied to the theory of complex spectra and the Russell-Saunders case is used to obtain the energy levels of one-electron spectra.

Photoabsorption by ground-state alkali-metal atoms.
TL;DR: In this article, principal series oscillator strengths and ground-state photoionization cross sections are computed for sodium, potassium, rubidium, and cesium, and the degree of polarization of the photoelectrons is also predicted for each atom.
