Аннотация
A workable basis of quark configurations s3, s2p and sp2 at light front has been constructed to describe the high-Q2 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 electroproduction.
