英文摘要	Results are presented on J/psi radiative decays to K+K- and (KSKS0)-K-0 based on a sample of 58M J/psi events taken with the BES II detector. A partial wave analysis is carried out using the relativistic covariant tensor amplitude method in the 1-2 GeV mass range. There is conspicuous production due to the f(2)(')(1525) and f(0)(1710). The latter peaks at a mass of 1740+/-4(-25)(+10) MeV with a width of 166(-8)(-10)(+5)(+15) MeV. Spin 0 is strongly preferred over spin 2. For the f(2)(')(1525), the helicity amplitude ratios are determined to be x(2)=1.00+/-0.28(-0.36)(+1.06) and y(2)=0.44+/-0.08(-0.56)(+0.10).
