Abstract
In the energy range from 1.05 to 1.38 GeV, the upper limits for the cross sections of e + e − → f 0(600)γ, f 0(980)γ, f 0(1350)γ, and f 2(1270)γ → π0π0γ processes have been established. Measurements are performed in accordance with the statistics gathered in experiment with a spherical neutral detector (SND) on the VEPP-2M e + e − collider. The resultant upper limits vary from 6 to 42 pb depending on the energy and the model.
