✦ Synopsis
Recent preliminary results based on 58 million J/I) events collected at the upgraded BESII are presented. The Partial Wave Analysis of the Jill, -+ yKI? and J/q -+ yr'r -in the mass region below 2.0 GeV for study of the structure around 1.7 GeV is reported. The mass of qC is mea.sured in five J/I/> decay channels. This talk also includes the search for some interesting sta.tes.
