The eigenvalues are calculated numerically. The properties of the wave functions, which depend on the potential parameter a, are illustrated for a given potential parameter ξ. It is shown that the wave functions are shrunk to the origin when the potential parameter a increases. We note that the energy levels ϵi (i[1,3]) decrease with the increasing potential parameter a but the energy levels ϵi (i[4,7]) first increase and then decrease with the increasing a.
