Excerpt from Upper Bounds on Scattering Lengths for Static Potentials Variational methods have proved to be of great value in the theoretical analysis of the problem of the scattering of a particle by a center of force. However, the utility of variational techniques in the more complicated problem of scattering by a compound system is considerably impaired by the fact that it is more difficult, in the many body problem, to construct accurate trial functions, and a variational calculation, using a poor trial function, will generally lead to poor results. In fact, these calculations will only be meaningful when accompanied by an affirmation of validity, using some reliable criterion. It is our purpose to present one such rigorous validity criterion for the case of zero energy scattering. The present discussion will, for the sake of clarity of presentation, be confined to the problem of scattering by'a static potential; the generalization to the more interesting problem in which the scatterer.
