Supersymmetric Proof to Count Bound State Nodes

A normalizable static supersymmetric bound ground state annihilated by the supergenerators has got zero number of internal nodes in the framework of one-dimensional supersymmetric quantum mechanics. The supergenerator transformations between excited superpartner bound states as combined with the standard technique of Wronskian provides an elegant and self-sufficient way to derive the equality of internal nodes amount to the number of consequent excitation.
