Resumen:
We calculate accurate bound states and resonances of two interesting perturbed Coulomb models by means of the RiccatiPadé method. This approach is based on a rational approximation to a modified logarithmic derivative of the eigenfunction and produces sequences of roots of Hankeldeterminants that converge rapidly towards the eigenvalues of the equation
