摘要：

Data on (p) over bar p --> eta pi(0) pi(0) pi(0) taken at beam momenta of 1.2 and 1.94 GeV/c reveal evidence for two I = 0 J(PC) = 2(-+) resonances in eta pi pi. The first, at 1645 +/- 14(stat.) +/- 15(syst.) MeV with width 180 (+40)(-21) +/- 25 MeV, decays to a(2)(1320)pi with L = 0. It may be interpreted as the q (q) over bar D-1(2) partner of pi(2)(1670). A strong signal is also observed just above threshold in f(2)(1270)eta with L = 0. It is 11-22 times stronger than is expected for the high mass tail of the 1645 MeV resonance. It can be fitted as a second 2(-+) resonance at 1875 +/- 20 +/- 35 MeV with width 200 +/- 25 +/- 45 MeV. A third resonance having J(PC) = 2(++) is observed at 2135 +/- 20 +/- 45 MeV with Gamma = 250 +/- 25 +/- 45 MeV, decaying to both a(2)(1320)pi and f(2)(1270)eta with L = 1. There is no evidence for resonances with decays to a(0)(980)pi, sigma eta or f(0)(980)eta.
