Abstract :
Data on View the MathML source are presented at 9 momenta 600–1940 MeV/c. A broad high mass 2+ resonance is observed in ηη with mass M = 1980 ± 50 MeV and width Γ = 500 ± 100 MeV. Also f0(1770) → ηη is observed with M = 1770 ± 12 MeV, Γ = 220 ± 40 MeV. The presence of a2(1660) is confirmed at all beam momenta and f0(2100) → ηη is also confirmed.
