Query: Comment on "Evidence for the Existence of Supersymmetry in Atomic
  Nuclei"   Metz et al PRL (83), 1542 (1999) have presented evidence for supersymmetry in
atomic nuclei but their model Hamiltonian fails to distinguish between
irreducible representations that occur with multiplicities greater than one.
This failure raises serious questions as to the validity of the evidence.
