摘要
Energies of singlet doubly excited states 2p(2) D-1, 3d(2) (1)G, 4f(2) I-1 of He isoelectronic series are calculated in the framework of the variational method by using Hylleraas-type wave functions and a real Hamiltonian. The results obtained show quantitatively the importance of electron correlation effects in the doubly excited states and they are in good agreement with some experimental data and other theoretical results.
