High precision calculations and QED effects for two- and three-electron atoms

Physica Scripta, 1993
Essentially exact results can now be obtained for the nonrelativistic energy and lowest-order relativistic corrections of helium. A combination of variational calculations and asymptotic expansion methods covers the entire singly-excited spectrum.
