Abstract
A procedure based on the exact solutions of multiple-step recursion relations with successive coefficients is shown to provide upper bounds to the bound-state energies of a class of anharmonic-oscillator potentials. Any finite set of energy levels can thereby be estimated to any accuracy. The associated wave functions are guaranteed to be normalizable.Keywords
