Computer simulation technique is used to study the scattering of 30 keV N 2 ions by the surface semichannels of a copper crystal. The specular reflection intensities of molecular and dissociated ions and the orientations of the reflected molecules are analyzed. The trajectory focusing is found to affect essentially the molecular scattering near the semichannel direction. A simple formula is obtained which relates the semichannel focusing energy directly to the interatomic potential.
