The analysis of high-energy photons and electrons interaction with nitrogen, oxygen and xenon molecules is represented. The typing of collisions on scattering with small and great momentum transfer is established. The data on cross sections of interactions of low-energy electrons with molecules are represented. The mathematical model of electron-photon cascade transport is represented. Ionizing and elastic scattering, molecular and electron level excitation, electron attachment to oxygen molecules are considered. Sources of data are stated. Data set is oriented on mathematical modeling of electron-photon cascade transport in gaseous medium.
