In this paper we present an approach to study the radiative decay modes of the J/ψ into a photon and one of the tensor mesons f 2(1270) , f′ 2(1525) , as well as the scalar ones f 0(1370) and f 0(1710) . Especially, we compare predictions that emerge from a scheme where the states appear dynamically in the solution of vector meson-vector meson scattering amplitudes to those from a (admittedly naive) quark model. We provide evidence that it might be possible to distinguish amongst the two scenarios, once improved data are available.
