Abstract：
A possible form of ρ⁰-ω mixing is proposed.The mixing coupling constant is determined by (ρ⁰,ω)→π⁺π^－ decay rates.The (ρ⁰,ω) positron-electron pair decay rates are calculated and it is found that the mixing effect contributes 9.4% enhancement to ρ⁰→e⁺e^－ and 2.6% raduction to ω→e⁺e^－ decay processes.
