Abstract
The processes e+eââηγ, Ï0γâ3γ 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(Ï0âηγ)=(3.21±1.39±0.20)Ã10â4,B(Ïâηγ)=(4.44â1.83+2.59±0.28)Ã10â4,B(Ïâηγ)=(1.373±0.014±0.085)Ã10â2,B(Ï0âÏ0γ)=(6.21â1.18+1.28±0.39)Ã10â4,B(ÏâÏ0γ)=(9.06±0.20±0.57)Ã10â2,B(ÏâÏ0γ)=(1.258±0.037±0.077)Ã10â3.
