Relativistic corrections for screening effects on the energies of hydrogenlike atoms embedded in plasmas
Abstract
The influence of relativistic and plasma screening effects on energies of hydrogenlike atoms embedded in plasmas has been studied. The Dirac equation with a more general exponential cosine screened potential has been solved numerically and perturbatively, by employing the direct perturbation theory. Properties of spectra corresponding to bound states and to different sets of the potential parameters have been studied both in nonrelativistic and relativistic approximations. Binding energies, finestructure splittings, and relativistic energy shifts have been determined as functions of parameters of the potential. The results have been compared with the ones known from the literature.

Scalar relativistic effects on energies of molecules containing atoms from hydrogen to argon.
Stationary direct perturbation theory is used to calculate a scalar relativistic correction to the species in the G3/99 test set. We observe that the relativistic energy almost always reduces atomization energies, electron affinities, and ionization potentials. Exceptions occur when s orbitals play a predominant role in the energy differences between reactants and products. The scalar relativistic energy, when added to G3 theory and the empirical parameters are reoptimized, gives slightly worse agreement with experiment. 
Relativistic corrections to the Zeeman effect in hydrogenlike atoms, positronium, and heliumlike atoms
An approximately relativistic theory of bound states which ensures the Poincare invariance of atomic systems to relative order (v/c)[sup 2] is used to derive the Zeeman interaction Hamiltonians correct to order [alpha][sup 3] and to all orders in m[sub e]/m[sub N] for arbitrary two body systems and three body systems. Previously neglected radiative corrections of order [alpha][sup 3] and recoil corrections of order [alpha][sup 3]m[sub 3]/m[sub N] are also included. For neutral systems, the linear Zeeman Hamiltonians are unitarily equivalent to the linear Zeeman Hamiltonians obtained by other authors in the past.
