Abstract
The case of the DELTA(1232)-resonance is examined as another striking example where the method of obtaining polynomial models of hadronic wa ve functions from QCD sum-rule moments fails because of non-convergenc e. It is found that polynomial models for the DELTA distribution ampli tude are completely undetermined. Additional constraints from QCD are therefore necessary.
