Моделирование образования треков в аморфных сплавах железа при облучении тяжёлыми ионами высоких энергий

An important process in the fundamental radiation in solid state physics and in applications is the process of the track formation at irradiates by high-energy heavy ions of different in their physical and chemical properties materials. The development of modern methods of analysis and studies of the structure of extended defects stimulates initiation of new experimental and theoretical research in this area. In the experimental work the track diameters 11.1 MeV/amu ion $^{132}$Xe, $^{152}$Sm, $^{197}$Au and 8.2 MeV/amu $^{238}$U ions in a number of amorphous alloys of iron and boron were measured using a small angle scattering of synchrotron radiation. In this work, a three-dimensional model of the thermal spike modified with phase transitions of the fusion was introduced and used to estimate the diameter of tracks all of the above ion-target combinations whose values were compared with experimental data. Accounting to the phase transitions made in this work to evaluate the tracks diameters significantly improves the agreement of the simulation results with experimental data.
