We report on our study on η photoproduction and electroproduction on the nucleon using an isobar model. The model contains nucleon Bron terms and contributions from t-channel vector meson exchange as nonresonant background. In addition to the dominant S_(11)(1535), we also include resonance contributions from D_(13)(1520), S_(11)(1650), D_(15)(1675), F_(15)(1680), D_(13)(1700), P_(11)(1710), and P_(13)(1720). Within this model we analyze recent η photoproduction data for differential and total cross sections, beam and target asymmetries, as well as JLab electroproduction data. Good agreement has been achieved. With the new cross section data from GRAAL [2], we show that besides the dominant S_(11)(1535), the second S_(11) resonance, S_(11)(1650), is required in order to extract S_(11)(1535) resonance parameters properly. In addition, the beam asymmetry data allow us to extract very small (< 0.1%) N~* → ηN decay branching ratios of D_(13)(1520) and F_(15)(1680) resonances because of the overwhelming s-wave dominance. Finally, the Q~2 dependence of S_(11) (1535) is extracted from two recent JLab electroproduction data. The model is implemented as a part of the MAID program.
