Abstract

A workable basis of quark configurations s(3), s(2)p and sp(2) at light front has been constructed to describe the high-Q(2) behavior of transition form factors and helicity amplitudes in the electroproduction of the lightest nucleon resonances,N1/2- (1535) and N1/2+ (1440). High-quality data of the CLAS Collaboration are described in the framework of a model which takes into account mixing of the quark configurations and the hadron-molecular states. The model allows for a rough estimate of the quark core weight in the wave function of the resonance in a comparison with high momentum transfer data on resonance clectroproduction.
