Abstract

The Q2 -dependence of the cross-section of semi-inclusive π-meson electroproduction has been studied in the low-energy range covering the nucleonic resonances. It has been found that the Q2 -dependence of these data differs from the behavior of the factorized cross-section for high energies. The analysis of ratios of measured to model-calculated cross-sections renders a simple polynomial function for introducing the Q2 -correction into the cross-section. This additional correction provides much better agreement between the experimental and calculated data.
