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 observations associated with the wave function are presented.
