  The statistical fluctuations of the ground-state energy and of the binding
energy of nuclei are investigated using both perturbation theory and
supersymmetry. The fluctuations are induced by the experimentally observed
stochastic behavior of levels in the vicinity of neutron threshold. The results
are compared with a recent analysis of binding-energy fluctuations by Bohigas
and Leboeuf, and with theoretical work by Feshbach et al.
