Abstract
The first results on the structure function in exclusive electroproduction at invariant masses of the final state of 1.5 GeV 1.8 GeV and in the range of photon virtualities 0.4 GeV GeV were obtained from data on beam spin asymmetries and differential cross sections measured with the CLAS detector at Jefferson Lab. The Legendre moments determined from the structure function have demonstrated sensitivity to the contributions from the nucleon resonances in the second and third resonance regions. These new data on the beam spin asymmetries in electroproduction extend the opportunities for the extraction of the nucleon resonance electroexcitation amplitudes in the mass range above 1.6 GeV.
