Directional Dependence of the Displacement Energy Threshold for a FCC Metal

Dynamical method computer experiments were used to map out the displacement energy threshold in a fcc metal as a function of the direction in which a primary knock-on atom is ejected from a lattice site. The displacement energy threshold for the [100] and [110] directions was about 22 eV and that for the [111] direction was 57 eV. A region of high displacement energy threshold was found in the interior of the stereographic triangle near the line between the [111] and [110] poles. The largest threshold energy in this region was 70–75 eV.
