Search for the decays $J/ψ\toγρϕ$ and $J/ψ\toγρω$

Using 58 million $J/ψ$ events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider, the decays $J/ψ\to γϕρ$ and $J/ψ\to γωρ$ are searched for, and upper limits on their branching fractions are reported at the 90% C. L. No clear structures are observed in the $γρ$, $γϕ$, or $ρϕ$ mass spectra for $J/ψ\to γϕρ$ nor in the $γρ$, $γω$, or $ρω$ mass spectra for $J/ψ\to γωρ$.
