Abstract
The process of electron-positron pair creation by a
high-energy electron in a medium is analyzed. The spectral
distribution over energies of created particles is calculated for
the direct and cascade mechanisms of the process. The Coulomb
corrections are included. The new formulation of the equivalent
photons method is developed which takes into account the influence
of multiple scattering. It is shown the effects of multiple
scattering can be quite effectively studied in the process under
consideration.
