Description
The model taking into account the contributions of the impulse approximation and dibaryon resonances with JP equalling 2+ and 3- is employed to calculate differential cross sections for the ed→eπ0d process (electron and π0-meson being detected). Single-nucleon amplitudes are determined by contributions of two mechanisms, namely the Born mechanism and the Δ-isobar excitation one, The momentum transfer square varies within the range of 0.005-2 GeV2. Most essential dibaryon effects are possible in the cross-sections at large π0-meson production angles
