摘要：

Data on the final state eta eta pi(0) are presented for beam momenta of 1350, 1525, 1642, 1800 and 1940 MeV/c. There is evidence for the presence of a broad high mass 2(+) contribution in eta-eta; the amplitude analysis fits it as a resonance with mass M = 1980 +/- 50 MeV and width Gamma = 500 +/- 100 MeV. It has the curious feature that it is produced dominantly with orbital angular momentum L = 1 in the final state and with component of spin +/- 1 along the beam direction. It contributes typically similar to 15-20% of the integrated cross section. In addition, the presence of a(2)(1660) is confirmed at all beam momenta. Also f(0)(2100) --> eta-eta is confirmed.
