Abstract: (Elsevier)

Inclusive η production by e + e − annihilation for cm energies between 4 and 5.2 GeV was studied. A strong η signal was observed at 4.4 GeV, produced predominantly in conjunction with a low energy photon suggestive of F F ∗ or F ∗ F ∗ production. From events containing a π ± , and η, and a low energy photon the F and F ∗ masses were found to be 2.03 ± 0.06 and 2.14 ± 0.06 GeV, respectively.
