Resumen:
We argue that Ansaripour (2010 Phys. Scr. 82 045008) obtained not the eigenvalues and eigenfunctions of the double-well oscillator, but those for a single-well anharmonic oscillator. We show that his eigenvalues obtained by means of the Riccati?Padé method are not as accurate as the reported number of digits suggests. More precisely, Ansaripour?s sequences of roots of the Hankel determinants converged to wrong limits.
