Resumo
Using the interaction potentials obtained in the framework of the density functional theory, the nuclear stopping powers are calculated for the H, D, T–Be, C, W, systems necessary for calculating the plasma–wall interaction in thermonuclear research, as well as for the Kr–Si, Kr–Ge, O–Si systems, used in ion implantation into semiconductors. In the collision energy range 10–1000 eV, the obtained data differ from the SRIM data by 15–70%. The presence of a potential well leads to the appearance of an additional peak in the nuclear stopping power at low energies. A comparison of the classical calculations of the transport cross section with the semiclassical ones showed their identity at energies up to 0.3 eV.
