Ambigous sets of partialwave amplitudes cannot intersect
Abstract
The correct set of partialwave amplitudes can sometimes be distinguished from ambiguous ones because it joins continuously, as a function of energy, to a lowerenegy set known unambiguously. If two sets intersect, however, this continuity criterion yields no unique answer. We show that such an intersection is in fact impossible in the usual experimental spin0 spin {1}/{2} scattering situation.
