Computer Simulation of Vacancy Clusters Distribution by Depth in Molybdenum Irradiated by Alpha Particles

Abstract

Computer simulation of vacancy clusters distribution by depth in molybdenum irradiated by alpha particles within Cascade probability method has been carried out. Cascade probability functions have been calculated taking into account energy losses for alpha particles in molybdenum and depending on number of interactions and depth of particles penetration. Microhardness comparison of calculations and modified experimental data show their satisfactory fit.

Development of an algorithm for calculating the concentration of radiation defects during ion irradiation

“…It is impossible to put expression in the form of (3) instead of ψ n (h )as a repletion appears in every term of cascade-probability function (CPF). Expression for ψ n (h ) used in the form [20]:…”

“…Previously, in most cases, in specific calculations, the simplest cascade probability function (CPF) was mainly used, this is not always justified, since the interaction path depends on the energy. It is necessary to study the behavior of the obtained CPFs, taking into account the energy losses for ions, to prove the properties that they must possess both from a physical and mathematical point of view, develop calculation algorithms and calculate the CPF depending on the number of interactions and the penetration depth of the particles, the primary knocked out atoms and concentration of radiation defects [18][19][20].…”
