Abstract

The SCF-formalism is modified to include as constraints in the variational procedure physical quantities defined by one-electron operators. Introducing empirical values for the expectation values of these operators, pseudo-eigenvalue equations are obtained whose solution will lead to self-consistent orbitals which are constrained to achieve the chosen empirical values.

Zusammenfassung

Die SCF Methode ist abgewandelt, um als Nebenbedingung in der Variationsmethode physikalische Eigenschaften einzuschließen, die durch Ein-Elektron-Operatoren definiert sind. Durch Einführung von empirischen Werten für die Erwartungswerte dieser Operatoren erhält man Pseudo-Eigenwert-Gleichungen, deren Lösung zu SCF-Orbitalen führt, die die gewählten empirischen Werte geben.

Résumé

On a modifié le formalisme de champ auto-cohérent à fin de pouvoir introduire les valeurs de propriétés physiques comme conditions sécondaires dans la méthode de variation. La solution des équations à valeurs propres, qu'on y obtient, permet d'obtenir des orbitales qui donnent les valeurs empiriques choisies.
