Abstract
To study channeling radiation produced by an ultra-relativistic electron beam channeling through a single crystal, a lattice potential of the crystal is required for solving the transverse motion of beam electrons under the influence of the crystal lattice. In this paper, we present a general formalism for this two-dimensional lattice potential of a crystal with a Lorentz contraction in the beam channeling direction. With this formalism, the lattice potential can be calculated from any given model of electron-ion interaction for an ultra-relativistic beam channeling in any crystal direction. This calculation of the lattice potential does not involve any additional approximation other than those originally in the electron-ion interaction model. The formalism presented should be the standard recipe of the lattice potential for studying the channeling radiation.
