  The stationary wave functions of fast electrons axially channeling in the
silicon crystal near [110] direction have been found numerically for integrable
and non-integrable cases, for which the classical motion is regular and
chaotic, respectively. The nodal structure of the wave functions in the
quasi-classical region, where the energy levels density is high, is agreed with
quantum chaos theory predictions.
