摘要：

A method for first order calculations which does not require an explicit partitioning of the Hamiltonian into zeroth and first order parts is presented. The method is equivalent to calculations with the Stern-heimer potential, except that the potential need not he calculated - only the full Hamiltonian appears in the equations. The method applied to the ground states of H-, He and Li+, for which Echart-type open shell functions are employed as the zeroth order functions, and approximate first order functions are computed variationally.
