Measurement of the cross sections and angular  distributions for ETA ETA production in two-photon interactions for W values in the range 1.096 (threshold) to 3.3 GeV.

The data represent an integrated luminosity of 383 fb-1 taken in and around  the Upsilon region of 9.43 to 11.02 GeV in E+ E- collisions, which includes  the largest part, 296 fb-1, at the Upsilon(4s).
