I. Introduction

Experimental data on deep-inelastic lepton-nucleon scattering must be corrected for electromagnetic radiative effects before drawing conclusions about the behavior of strong interactions at short distances (scaling properties, structure functions, and so on). For charged-lepton-nucleon scattering the radiative corrections due to the lepton are routinely applied to data. (1) The corresponding calculation for neutrino-nucleon scattering is inevitably model-dependent, and this fact, combined with the relatively poor statistics of existing neutrino experiments, has led to the neglect of radiative corrections in this case. In the near future, experiments on neutrino scattering will yield more precise results, for which radiative corrections should not be neglected. In this paper we present a numerical study of these corrections based on the parton-model calculation of Kiskis. (2) Our results are not exact; they depend slightly on the details of the parton model used, and should only apply in the truly deep-inelastic region. We have evaluated the radiative-correction factors to a wide selection of differential cross sections for various energies and types of incoming neutrinos, chiefly muonic ones. They are typically around 5-10%, except in kinematic regions where the cross section is negligible.
