| Abstract: | We report on an experiment on electroproduction in the resonance region in the mass range 1505 ? W ? 1715 MeV. Data have been taken at q2 = 0. 22, 0.6 and 1 GeV2. The angular distributions obtained support that η production proceeds mainly through S-wave excitation due to the resonance S11(1535).The total cross section of the formation of this resonance decreases much more slowly with increasing momentum transfer than the total ep cross section. |
