Description

The intensity of scalar a0(980), f0(980) and tensor a2(1320), f2(1270) mesons production at VEPP-2000 (BINP, Novosibirsk) and, possibly, the upgraded DAΦNE (Frascati, Italy) in the processes e+ea0(f0, a2, f2)γ is calculated with the help of VDM and the kaon loop model (for scalar mesons case). The processes e+ea2(f2)γ have not been seen in the energy region 1.52.0 GeV. It turned out that at this energies σ(e+ea2(f2)γ)10 pb and σ(e+ea0(f0)γ)0.1 pb. Photon angle distribution, the spin density matrices of a2 and f2 and the background situation will be reported also
