摘要

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 →π~0π~0γ 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.
