Resumen:
We calculate accurate eigenvalues of a bounded oscillator by means of the RiccatiPadé method that is based on a rational approximation to a regularized logarithmic derivative of the wavefunction. Sequences of roots of Hankel determinants approach the model eigenvalues from below with a remarkable convergence rate.
