Resumen:
We analyze a recent discussion of one-dimensional quantum-mechanical models with a perturbation produced by a delta-function potential. We show that theauthors failed to derive a correct transcendental equation for the eigenvalues inthe case of the Morse oscillator because they omitted the contribution of thecontinuum spectrum in the basis set.
