Electroproduction of η-meson at the S"1"1 (1535) resonance - Beck, U.; Becks, K.H.; Burkert, V.; Drees, J.; Dresbach, B.; Gerhardt, B.; Knop, G.; Kolanoski, H.; Nietzel, C.; Schlosser, E.; Muller, H.; Stier, H.E.; et al. (Elsevier)
The reaction e^- + p -〉 e^- + p + η has been studied in the region of the S"1"1 (1535)-resonance by detecting the recoil proton in coincidence with the scattered electron. The reaction has been observed at three four-momentum transfers of the virtual photon: q^2 = 0.2, 0.28 and 0.4 (GeV/c). First results of the differential cross section measurements are given and compared with quark model calculations.
