摘要: We show that the shape of kinetic energy distribution in radiation-induced thermal spikes may be described using a dimensionless number, proportional to (volume) 2/3 /(surface area), known as compactness. The disorder produced Ni 3 Al increases with compactness because spike cooling rate, which determines time available for disordering, decreases On other hand, Frenkel pair production is inversely correlated longer lifetimes enhance vacancy–interstitial recombination.
