Study of the Processes e+ e- --> eta gamma, e+ e- --> pi0 gamma --> 3 gamma in the c.m. Energy Range 600--1380 MeV at CMD-2

The processes e+e−→ηγ, π0γ→3γ have been studied in the c.m. energy range 600–1380 MeV with the CMD-2 detector. The following branching ratios have been determined: B(ρ0→ηγ)=(3.21±1.39±0.20)×10−4,B(ω→ηγ)=(4.44−1.83+2.59±0.28)×10−4,B(ϕ→ηγ)=(1.373±0.014±0.085)×10−2,B(ρ0→π0γ)=(6.21−1.18+1.28±0.39)×10−4,B(ω→π0γ)=(9.06±0.20±0.57)×10−2,B(ϕ→π0γ)=(1.258±0.037±0.077)×10−3.
