Abstract
The extension to bound-state problems of the variational bound formulation of scattering theory is considered. The simple decaying boundary condition allows a wider class of projection operators than in scattering theory, and they can be used to arrange an accurate wave-function calculation. The method retains the extremum property of the Ritz principle.Keywords
