Description
The two-body correlation method, proposed by Wilets et al. and developed by the authors for calculating the correlation structure of light atoms, is further investigated and applied to He-like ion excited states. In this formalism, the variational calculation of the full atomic wave function is predicted in detail. The calculated atomic correlation energy results agree very well with that of other more complicated correlation methods such as CI and 1/Z perturbation expansion etc
