Annotation It is shown that location of target atoms, specified by the structure geometry, define the distribution of impact parameters and energy transfer which strongly differs from the distribution of random location of targets. Considering model of solid spheres, energy spectrum of reflected atoms and probability of single or multiple collisions with the structure are found. Increase in the energy efficiency with respect to the disordered structure is established. Possibility and conditions of realizations of collisions with the second layer atoms omitting first ones are demonstrated.
