Abstract
The kinematical difference between the description of radiative effects for fixed vs a fixed scattering angle in the elastic lepton-proton ()-scattering is discussed. The technique of calculation as well as explicit expressions for radiative corrections to the lepton current in unpolarized elastic -scattering for these two cases are presented without using an ultrarelativistic approximation. A comparative numerical analysis within kinematic conditions of Jefferson Lab measurements and MUSE experiment in PSI is performed.
