We investigate whether known properties of the η' meson are consistent with its being the Goldstone boson of the spontaneously broken anomaly-free R symmetry required in the light gluino scenario. We fit the masses and 2γ decays of the η and η' mesons, and also their production in radiative J/ψ decays. We find that the η-η' system is well-described in the light gluino scenario, if mλ≃ (84-144) MeV and <λλ> ≃ -(0.15-0.36) GeV3. These values are in the range expected when the gluino gets its mass entirely from radiative corrections.
