Abstract :
Data taken with the Crystal Barrel detector on p̄p→ηη and ηη′ are presented from 600 to 1940 MeV/c. The f0(2105) appears strongly in the ηη channel with mass and width consistent within errors with earlier data. It is produced strongly in p̄p interactions, but with large branching ratio to ηη compared with ππ. This is incompatible with an unmixed non-strange qq̄ state.
