Abstract
The previous results of J/psi radiative decays from MARKIII, DM2, Crystal Ball and BESI are briefly reviewed in this talk. The main part of this talk focuses on presenting the recent results from BESII 58 million J/psi data, including the Partial Wave Analysis (PWA) results, the measurement of eta_c mass, as well as search for some interesting states.
