N2 - Using 53pb-1 of e+e- annihilation data taken at s=3.686GeV, a comprehensive study has been made of the radiative decays of samples of 5.1 million J/ψ and 24.5 million ψ(2S) into pairs of pseudoscalar mesons, π+π-, π0π0, K+K-, KS0KS0, and ηη. Product branching fractions for the radiative decays of J/ψ and ψ(2S) to scalar resonances f0 (1370, 1500, 1710, 2100, and 2200), and tensor resonances f2 (1270, 1525, and 2230) have been determined, and are discussed in relation to predicted glueballs. For ψ(2S) radiative decays the search for glueballs has been extended to masses between 2.5 GeV and 3.3 GeV.
