The differential cross section for the process p(e,e′p)η has been measured at Q2=2.4 and 3.6 (GeV/c)2 at center-of-mass energies encompassing the S11(1535) resonance. The latter point is the highest-Q2 exclusive measurement of this process to date. The resonance width and the helicity-1/2 transition amplitude are extracted from the data, and …
