Observation of resonances in the reaction (p)over-bar-p ->pi(0)eta eta at 1.94 GeV/c

Antiproton-proton annihilation into pi(o)eta eta has been studied with the Crystal Barrel spectrometer at CERN at an incident beam momentum of 1.94 Ge V/c. The data were taken with a trigger requiring neutral final states. A n ew isovector state, the alpha(2)(1660) decaying to pi(o)eta, is observed. I n the eta eta invariant mass region around 2.1 GeV/c(2), strong production of a heavy resonance is required, but our analysis does not distinguish bet ween J(P) = 0(+), 2(+) and 4(+). The production of the fo(1500) in reaction s in flight is also observed.
