Inclusive electron spectrum in the region of pion production in electron-nucleus scattering and the effect of the quasi-elastic interaction

We have carried out a calculation of the inclusive electron scattering cross sectionoff oxygen in the kinematical region corresponding to beam energies between 700 and 1200 MeV, where quasielastic scatteringand single pionproduction are the dominant reaction mechanisms. The formalism developed and successfully applied to describe quasielastic scatteringhas been extended to include both {delta} production and nonresonant pionproduction. The results are in fairly good agreement with experimental data over the whole range of energy transfer, including the dip region between the quasielastic peak and the first resonance.
