英文摘要	We consider all available data on radiative decays of J/Psi to the J(P) = 0(-) final states in rho rho, omega omega, K(K) over bar, phi phi, eta pi pi, and kappa K; here kappa refers to the K pi S-wave. They are fitted to a single Breit-Wigner resonance having s-dependent widths proportional to the available phase space in each channel. This resonance has a K-matrix mass 2190 +/- 50 MeV and a full width at half maximum of 850 +/- 100 MeV; errors are mostly systematic. Decays are flavour-blind within errors, suggesting it is the 0(-) glueball predicted near this mass by lattice gauge calculations. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
