  In this article a new analytical description of the effective interaction
potential for a charged particle in the field of two interfering laser beams is
presented. The potential dependence on the lasers intensities, orientation and
parameters of the particle entering the considered system is analyzed. It is
shown for the case of arbitrary lasers crossing angle that for different values
of projectile velocity the attracting potential becomes a scattering one so
that the channel axes and borders interchange each other. In addition the
projectile radiation spectral distribution is given and general estimations on
the expected beam radiation yield are outlined.
