On the preparation of data for modeling of the photons and electrons transport
Collisions experienced by photons and electrons with energies of 100 eV - 1 GeV during transport in matter are considered: photoabsorption, Compton and coherent scattering of photons, the formation of electron-positron pairs by them; elastic scattering of electrons, impact ionization, bremsstrahlung and excitation of atoms of the medium. The method is presented for a unified presentation of cross-sectional data in the form of tables of probability distributions, the argument of which is always a random variable uniformly distributed from zero to one. Tables are used by mathematical models of radiation transfer to model the absorption and scattering of photons and electrons.
