Using 53 pb(-1) of e(+)e(-) annihilation data taken at root S = 3.686 GeV, a comprehensive study has been made of the radiative decays of samples of 5.1 million J/psi and 24.5 million psi(2S) into pairs of pseudoscalar mesons, pi(+)pi(-,) pi(0)pi(0), K+K-, (KSKS0)-K-0 and eta eta. Product branching fractions for the radiative decays of J/psi and psi(2S) to scalar resonances f(0) (1370, 1500, 1710, 2100, and 2200), and tensor resonances f(2) (1270, 1525, and 2230) have been determined, and are discussed in relation to predicted glueballs. For psi(2S) radiative decays the search for glueballs has been extended to masses between 2.5 GeV and 3.3 GeV.
