摘要：

We analyze the existing data on electroproduction of eta mesons in the region of W approximate to 1.5 GeV, and extract an electrostrong form factor for the N*(1535) electroexcitation and decay into the eta-N channel, which is found to be relatively insensitive to the uncertainties of the effective Lagrangian approach. This extracted quantity is of interest in the QCD description of relevant baryons.
