A way of calculation of molecular effect in stable damage buildup in crystalline lattice under accelerated ion irradiation that takes into account nonlinear energy spikes is described, it is shown that the length of cubic cell edge influences only on the level of critical vacancy concentration and has no influence on coincidence of experimental and calculated curves.
