On the coherent radiation of relativistic electrons and positrons in crystal in the range of high energies of gamma-quanta

yesThe formulae for the cross-section of coherent radiation of high energy gamma-quanta by relativistic electrons and positrons in crystal taking into account the contribution of the second Born approximation into radiation are obtained. The dependence of the radiation cross-section in the field of atomic plane on the sign of charge of the particle is consideredBelgorod State Universit
