THE USE OF ELECTRONIC COMPUTERS TO CALCULATE RADIATION DISTURBANCES IN METALS,
Abstract
The analysis leads to the following general conclusions: (1) The threshold energy of the formation of a Frenkel pair during collisions in the directions <100> and <110> lies around 25 ev, and for the direction <111>, around 85 ev. (2) A focused transfer of displacements along the direction <110> is observed at E < 30 ev, along the direction <100>, at E < 40 ev. The energy losses for one collision are 0.7 and 7 - 8 ev respectively. (3) More substituted atoms than displaced atoms arise in the region of the disturbance. (4) If the energy of the primary atom exceeds the threshold energy only slightly, Frenkel pairs of different types are formed, but the positions of the interstitial atoms are different from those proposed in works. (5) At low energies the motions of atoms resemble thermal peaks; however, energy transfer in the peak is sharply anisotropic. The calculated problems do not at all exhaust the possibilities of this method of studying condensed phases. It is proposed to increase the number of atoms in the model and find a more precise definition of the law of atomic interaction. (Author)
