Abstract
The coherent scattering of photon in the Coulomb field (the Delbr\"uck scattering) is considered for the momentum transfer in the frame of the quasiclassical operator method. In high-energy region this process occurs over rather long distance. The process amplitude is calculated taking into account the multiple scattering of particles of the intermediate electron-positron pair in a medium. The result is the suppression of the process.
