In the energy range from 1.05 to 1.38 GeV, the upper limits for the cross sections of e{sup +}e{sup -} {yields} f{sub 0}(600){gamma}, f{sub 0}(980){gamma}, f{sub 0}(1350){gamma}, and f{sub 2}(1270){gamma} {yields} {pi}{sup 0}{pi}{sup 0}{gamma} 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{sup +}e{sup -} collider. The resultant upper limits vary from 6 to 42 pb depending on the energy and the model.
