摘要：

Fermilab experiment E835 has studied reactions (p) over barp ->pi(0)pi(0),pi(0)eta,eta eta, pi(0)eta(') and eta eta(') in the energy region of the chi(c0)(1(3)P(0)) from 3340 MeV to 3470 MeV. Interference between resonant and continuum production is observed in the pi(0)pi(0) and eta eta channels, and the product of the input and output branching fractions is measured. Limits on resonant production are set for the pi(0)eta and pi(0)eta(') channels. An indication of interference is observed in the eta eta(') channel. The technique for extracting resonance parameters in an environment dominated by continuum production is described.
