Many-body theory, relativistic

For systems containing light elements, however, Eq. (2) currently offers the most accurate method for calculating of Ep from first principles and for the estimation of E g,.,. for the calibration of non-relativistic many-body theory. For diatomic molecules high precision accurate numerical methods are available for the calculation of Epp, and, furthermore, Egg,., is about an order of magnitude larger than Ep for light elements. 

Highly-ionized atoms DHF calculations on isoelectronic sequences of few-electron ions serve as the starting point of fundamental studies of physical phenomena, though many-body corrections are now applied routinely using relativistic many-body theory. Relativistic self-consistent field studies are used as the basis of investigations of systematic trends in ionization energies [137-144], radiative transition probabilities [145-148], and quantum electrodynamic corrections [149-151] in few-electron systems. Increased experimental precision in these areas has driven the development of many-body methods to model the electron correlation effects, and the inclusion of Breit interaction in the evaluation of both one-body and many-body corrections.
