These topics include the decay J/psi yields gamma K anti K where the final state resonances f'(1515), theta(1700) and xi(2200) have been analyzed. The decay J/psi yields (gamma vector vector) is presented in three final states, J/psi yields gamma phi phi, gamma rho rho and gamma omega omega , providing the first measurement of the eta/sub c/ spin-parity (in gamma phi phi) and evidence for structures (in gamma rho rho and gamma omega omega ) near 1.7 GeV. 24 references.
