Abstract : A calculation of contributions from singly excited states to the second order perturbation theory energy of an N-electron atom or ion was carried out. A number of integrals relevant to interactions between 1s, 2s, and 2p hydrogen atomic orbitals are evaluated and tabulated. Comparison between calculated and observed term differences and ionization potentials shows fair agreement. (Author)
