✦ Synopsis

With the ire@ of the variation principie a necessary condition is derived for wavefunctionsbf the form Cpo f x in order that they arc solutions of the Schrtidinger equation. It is then shown that variationaIly optimal approximate !cnvcfuncticns aIso satisfy tllis condition and that it may be used to abtain the secular equations in an alterxtive fixin, Finally two new dja~o~~lization algorithms are. given with nn illustrative example.
