Results from the previous measurements in radiative decays are updated and compared with the hadronic decays. In particular, data which are relevant to understand the nature of the theta(1720), iota(1440) and/or E(1420), are presented. A preliminary analysis of a systematic study of direct J/psi decays into the vector(J/sup PC/= sup -- ) and the tensor (J/sup PC/=2 sup ++ ) mesons are presented. Some vector-scalar decays are discussed. Among the baryonic modes, observation of several SU(3) violating decays is reported. 23 refs., 10 figs. (ERA citation 11:005952) 收起
