摘要A combined fit is presented to data on (p) over barp annihilation in flight to final states eta pi (0)pi (0), pi (0)pi (0), eta eta, eta eta' and pi (-)pi (+). The emphasis lies in improving an earlier study of eta pi (0)pi (0) by fitting data at nine ii momenta simultaneously and with parameters consistent with the two-body channels. There is evidence for all of the I = 0, C = +1 (q) over barq states expected in this mass range. New resonances are reported with masses and widths (M, Gamma) as follows: J(PC) = 4(-+) (2328 +/- 38, Gamma = 240 +/- 90) MeV, 1(++) (1971 +/- 15, 240 +/- 45) MeV, 0(-+) (2285 +/- 20, 325 +/- 30) MeV, and 0(-+) (2010(-60)(+35), 270 +/- 60) MeV. Errors on the masses and widths of other resonances are also reduced substantially. All states lie close to parallel straight line trajectories of excitation number vs. mass squared.
