“…It should be noted that many works have been devoted to the problems of radiation defect formation during the interaction of ions with matter, for example [2][3][4][5][6][7][8][9][10]. Energy losses due to ionization and excitation of the electron shells of the atoms of the medium were not considered, so the simplest CPF was used.…”

“…Simultaneously, it is needful take into consideration the full "physical" picture of the interaction process considering the types of falling particles (light or heavy) [4,5]. When computing probabilistic characteristics difficulties arise in the case of ion irradiation, problems associated with the complexity of the mathematical description of these processes which served to create mathematical models describing the phenomena of the formation of vacancy clusters in dynamics [6][7][8][9][10].…”

The consumption of materials is growing every day, which means that we will increasingly have to cope with the problems of natural resources and supply. Therefore, humanity is forced to expand its resource base finding ways to use existing raw materials more efficiently, turn previously unusable substances into useful materials and also produce completely new materials from substances that are available in abundance. One of the ways to create new materials is to irradiate a substance with charged ions. The article discusses this technique based on the cascade-probabilistic method, the purpose of which is to obtain as well as the next ensuing use of cascade-probabilistic functions (CPF) considering energy losses for ions. The CPF computations were executed depending on the number of collisions and the depth of surveillance for various incident ions and samples. When computing cascade-probabilistic functions and spatial distributions of vacancy clusters patterns of conduct and finding the real resulting region in gold and silver alloys were obtained. Selection of step and boundaries for calculation were automated. Results of the calculations performed are illustrated in the form of graphs and tables.
