Perrier, J

Recent results on the J/psi, iota(1440), and theta(1690) from the Crystal Ball, DM2, and Mark III collaborations are presented together with preliminary results on charmonium states from the CERN-ISR R704 experiment. The J/psi two-body decays into a vector and a pseudoscalar meson are discussed; these results provide information about the quark content of the eta and eta' and are relevant to models in which these states are mixed with glueballs. New spin-parity determinations of the iota(1440) and theta(1690) are presented, as well as several recent branching ratio measurements including evidence for the decay theta(1690) ..-->.. ..pi../sup +/..pi../sup -/. 18 references.
