In this talk, the analysis results onJ/&psgr;→&ggr;&pgr;0&pgr;0,&ggr;&eegr;&eegr;,&ggr;&eegr;&eegr;′and&ggr;&eegr;′&eegr;′,based on BES9.0×106 J/&psgr;data, are reported and the evidences for the existence of &xgr;(2230) are presented. The results forJ/&psgr;→&ggr;&pgr;+&pgr;−&pgr;+&pgr;−,using the partial wave amplitude analysis (PWA), are obtained. We also reported the analysis results from&khgr;cJdecays. ©1998 American Institute of Physics.
