  A mode coupling calculation which previously explained the Mott gap collapse
induced in cuprates by electron doping is applied to the analogous problem of
hole doping. A plateau in the q-space susceptibility is found to inhibit the
rate of susceptibility divergence as T goes to 0. This effect could reconcile
neutron and NMR measurements of the correlation length in this regime, and
clarify the issue of proximity to a quantum critical point.
