Since the revelation of the narrow resonance at 2220 MeV in the KK-bar final states of the radiative decay J/Psi..-->..deltachi at SLAC, much theoretical and experimental effort has been devoted to the understanding of this unusual object. Theoretical explanations range from the conventional to the exotic. The experimental evidence, however, rests solely on one experiment and is not of sufficient quality to distinguish among the intriguing possibilities. We describe an experiment which would be ideal to measure precisely the properties of the xi, including its mass, width, and angular momentum.
