Add to ORKGWe calculate accurate eigenvalues of a bounded oscillator by means of the Riccati–Pade 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.Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicada
