## Abstract In this paper we present a simple method within the coupled Hartree–Fock framework to calculate the 1__s__2__s__ ^3^__S__ state of helium and heliumlike ions. The results are in very good agreement with those obtained by the use of multiterm correlated wave functions. Some interesting o

A complete-model-space (CMS) valence-universal coupledcluster (VU-CC) method is applied to the problem of calculating the energies and wavefUnctions for the 2s2 'S and 2p2 'S quasidegenerate states of Be. The difficulties encountered with this problem have supported the viewpoint that CMS formulatio
