Including a distribution of threshold displacement damage energy on the calculation of the damage function and electron's Non Ionizing energy Loss

The Norgett-Robinson-Torrens displacements per atom function is commonly used to estimate the amount of atomic displacement produced by incident energetic particles. At low energy, this defined as a step presenting single threshold damage energy. But materials have different crystallographic orientation. Molecular dynamic simulations show that continuously varying energy probability best suited represent region. This work proposes method introduce in NRT continuous distribution. impact change on region evaluated electrons' Non Ionizing Loss.
