Dynamics of Bound State Populations for Channeled Electrons/Positrons

When electrons or positrons are planar channeled through a crystal, the spectrum of bound energy states forms and one can observe so-called channeling radiation. The intensity of channeling radiation depends on populations of bound energy levels. These populations change during projectiles motion through a crystal that, in turn, influences the CR intensity. In this manuscript we present theoretical model and computer codes to investigate the bound energy spectra of planar-channeled electrons and positrons and to obtain the initial populations of bound states. Solving the kinetic equations and using some approximations we explore the dynamics of bound state populations. In the future taking into account the dechanneling processes more realistic picture of evolution of bound state populations will be giving.
