Atomic Structure Calculations of Helium with Correlated Exponential Functions
The technique of quantum electrodynamics (QED) calculations of energy levels in the helium atom is reviewed. The calculations start with the solution of the Schrödinger equation and account for relativistic and QED effects by perturbation expansion in the fine structure constant <inline-formula&g...
