Abstract
It is shown that finite difference energies for the Schrodinger equati on can be markedly improved by forming a linear combination of the com puted energy and the expectation value of an operator derivable from t he virial theorem. One- and two-dimensional test calculations are repo rted. (C) 1997 Published by Elsevier Science B.V.
