摘要：

New measurements of the reaction e+ e- --> omega-pi confirm previous evidence for the decay rho'1 --> omega-pi and provide a strong constraint on the mass of the rho'1. The results from a detailed analysis of these data are compared with those from a corresponding analysis of new data on the reaction e+ e- --> rho-pi. It is shown that GAMMA(rho'1 --> omega-pi) approximately 1/3 GAMMA(omega'1 --> rho-pi) in accord with expectation. This identification of a strong rho'1 --> omega-pi decay supports a previous claim that the rho'1 and the C(1480), observed in the phi-pi channel, cannot be different manifestations of the same particle.
