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