For pt.I see ibid., vol.16, no.17, p.4001-11 (1983). The general Schrodinger equation is converted into equivalent (2t+1)-term recurrences by the generalised Lanczos construction of the basis. Then, the exact bound states are given by the t-parametric determinantal formula. Finally, the values of the free parameters are shown to follow from the Hill type normalisability requirement.
