  We analytically analyse the motion of a nonrelativistic charged particle in a
cylindrical single capillary. The effective potential for interaction of a
charged particle with the inner surface of a capillary is derived as a sum of
the averaged atomic potential of the capillary wall surface and the induced
potential defined by collective surface excitations. We have shown that under
certain conditions this potential becomes attractive and may hold a particle in
a bound state due to the surface excitations that defines a so-called surface
channeling regime of motion. For the first time we have evaluated the induced
potential revealing two limits to form either a well or a barrier that are
delineated by the ratio of the insulator plasmon frequency to the frequency
defined by the particle motion in a capillary.
