Peculiarities of a wake potential formation due to a polarization interaction of channeling electron with ionic crystal solid state plasma

Under the influence of electric and magnetic fields generated by a nonrelativistic electron moving in the regime of a plane channeling, the induced time dependent ion electric dipole moments of a crystal medium are calculated. Accounting the causality principle for this dipole system a general scalar potential which can be named a ''wake'' one is found. It is shown that this potential in some crystallographic directions (for example, in ionic crystals) may lead to an essential reverse influence on the regime of the channeling particle motion
