摘要：

The pi(+)pi(-) invariant mass distribution produced in <(p)over bar p> annihilation at rest and recoiling against eta mesons exhibits large interference between the amplitudes for rho eta and omega eta production. The interference can be quantitatively described within the framework of rho-omega interference. We find full coherence between the rho eta-omega eta production amplitudes and a vanishing relative production phase. The implications of this result for <(p)over bar p> annihilation dynamics are discussed. (C) 1997 Elsevier Science B.V.
