Abstract
An exactly soluble base problem for atomic systems is presented which appro ximates the atomic Hamiltonian as a sum of identical one-electron operators . The eigenfunctions of the one-electron operator consist of a radial funct ion multiplied by a spherical harmonic. Energies for many-electron atoms ar e found by summing the one-electron energy eigenvalues according to the Pau li principle. These energies are rigorous lower bounds to the exact energie s.
