The structure function approach and the parton picture, developed for the theoretical description of the deep inelastic electron-proton scattering, also proved to be very effective for calculation of radiative corrections in Quantum Electrodynamics. We use them to calculate radiative corrections to the cross section of electron-proton scattering due to electron-photon interaction, in the experimental setup with the recoil proton detection, proposed by A. A. Vorobyev to measure the proton radius. In the one-loop approximation, explicit expressions for these corrections are obtained for arbitrary momentum transfers. It is shown that, at momentum transfers small compared with the proton mass, various contributions to the corrections mutually cancel each other with power accuracy. In two loops, the corrections are obtained in the leading logarithmic approximation.

为深层非弹性电子-质子散射的理论描述而开发的结构函数方法和parton图片也被证明对于计算量子电动力学中的辐射校正非常有效。我们使用它们来计算由于电子-光子相互作用而引起的电子-质子散射截面的辐射校正，这是由AA Vorobyev提出的用于测量质子半径的反冲质子检测的实验装置。在单回路逼近中，针对任意动量传递获得了这些校正的显式表达式。结果表明，与质子质量相比，在动量传递较小的情况下，对校正的各种贡献会以功率精度相互抵消。在两个循环中
