TLDR
In this article, a theoretical scheme for describing atomic spectra is developed, which differs from the current one in three main ways: (i) the nuclear charge Z enters explicitly into all predictions made with the new scheme, and (ii) certain effects of configuration interaction are allowed for in the first approximation.About:

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.

Atomic polarizabilities and shielding factors
TL;DR: In this article, a detailed discussion of the methods of calculating atomic polarizabilities and shielding factors and the relationships between them are demonstrated, and a more accurate procedure, the coupled Hartree-Fock approximation, is described.

Relativistic calculation of atomic structures.
TL;DR: In this article, the state of the art in relativistic calculation of atomic structures is surveyed and the theory is modelled on the practice in non-relativistic calculations, using many-particle wave functions built from Dirac central field spinors.

Applications of B-splines in atomic and molecular physics
TL;DR: In this article, the main properties of B-spline basis sets and why they are useful to solve different problems in atomic and molecular physics are discussed and an extensive reference list of theoretical works that have made use of them up to 2000 is provided.

Recent Developments in Perturbation Theory
TL;DR: Perturbation theory is designed to deal systematically with the effects of small perturbations on physical systems when the effects are mathematically too difficult to calculate exactly, and the properties of the unperturbed system are known as mentioned in this paper.
