Description
The intensity of scalar $a_0(980)$, $f_0(980)$ and tensor
$a_2(1320)$, $f_2(1270)$ mesons production at VEPP-2000 (BINP,
Novosibirsk) and, possibly, the upgraded DA$\Phi$NE (Frascati, Italy) in the
processes $e^+e^- \to a_0 (f_0$, $a_2$, $f_2) \gamma$ is
calculated with the help of VDM and the
kaon loop model (for scalar mesons case).
The processes $e^+e^-\to a_2(f_2)\gamma$ have not been seen in the energy
region $1.5-2.0$ GeV. It turned out that at this energies
$\sigma(e^+e^-\to a_2(f_2)\gamma)\sim 10$ pb and $\sigma(e^+e^-\to
a_0(f_0)\gamma)\sim 0.1$ pb.
Photon angle distribution, the spin density matrices of $a_2$ and $f_2$
and the background situation will be reported also
