摘要：

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