Abstract
In general, an -matrix or phase-shift analysis yields several ambiguous solutions that give identical fits to the data. Computer studies of a simple system involving only a few resonances suggest that the unphysical solutions show characteristic correlations (pseudoresonances) in different partial waves near a true resonance in one partial wave. Therefore, the physical solution requires the fewest resonant states. We apply this criterion to an analysis of .
