Abstract:

It is shown that the second-order energy correction calculated by means of the Hylleraas variation principle with an approximate zero-order function need bear no special relationship to the true value. In particular, there may be considerable deviation from the true value even if the approximate zero-order wavefunction is nearly exact, unless one requires that the trial function be orthogonal to the approximate zero-order function.
