Supersymmetric Proof to Count Bound State Nodes

A normalizable static supersymmetric bound ground stateannihilated by the supergenerators has got zero number of internalnodes in the framework of one-dimensional supersymmetric quantummechanics. The supergenerator transformations between excitedsuperpartner bound states as combined with the standard techniqueof Wronskian provides an elegant and self-sufficient way to derivethe equality of internal nodes amount to the number of consequentexcitation.
