β¦ Synopsis
With the increasing accuracy of experimental data obtained from high resolution techniques, it becomes necessary to introduce relativistic effects into the study of atomic structure. A general method of evaluating relativistic effects in atomic structure problems is described. Each operator is expressed as a product of irreducible tensors whose matrix elements are calculated using Racah algebra techniques. The question at what stage the Breit interaction should be included in the Hamiltonian is discussed.

A computationally effkknt method to account for two-electron relativistic effects in a spin-free no-pair Hamiltonian has been investigated. The approach amounts to a rno~~~t~on of integrak familiar from ~o~-re~at~v~st~~ theory and is therefore compatible with a variety of different correfation treat
A review is given of many-body perturbation methods, particularly in the all-order and coupled-cluster forms. Relativistic many-body schemes are analyzed in terms of one-and two-photon potentials, derived by means of QED. A complete second-order (nonradiative) calculation for He-like ions is present
