dc.descriptionThe radiative decays $V\to Sγ$ and $S\to Vγ$ with $V=ρ, ω, ϕ$ and $S=a_0, σ, f_0$ are calculated within the framework of the Linear Sigma Model. Current experimental data on the $ϕ\to f_0γ$ and $ρ\toσγ$ branching ratios and the ratio $Γ(ϕ\to f_0γ)/Γ(ϕ\to a_0γ)$ are satisfactorily accommodated in our approach. We also estimate the decay widths of the $f_0,a_0\toργ,ωγ$ transitions. All the processes considered are of interest for ongoing experimental programs in Frascati, Jülich and Novosibirsk.
