Abstract

A variational method for calculating an approximate excited-state wavefunction which has maximum ovelap with the corresponding exact wavefunction, recently employed by Messmer, is rederived from a generalization of the classical procedure of Weinstein. The method requires knowledge of the appropriate exact energy level, but no explicit constraints are required in the variation process.
