Calculation of Nuclear Stopping in the Semiclassical Approximation

The results of calculating nuclear stopping in the semiclassical approximation for the H–Be, H–C, H–W, O–C, O–Be, and O–Al systems are presented. It was found that, in the presence of a well in the interatomic-interaction potential, an additional maximum appears in the dependence of the nuclear stopping on the energy of the bombarding particles. When using the universal potential without a well, this feature is absent. It is shown that, by means of scaling, the data obtained for systems with hydrogen are recalculated for collisions with the participation of D and T hydrogen isotopes. The results obtained are in good agreement with classical calculations, which is explained by the fact that large scattering angles make the main contribution to the nuclear stopping and the applicability criterion changes to the condition that angular momentum $$\ell $$ ≫ 1.
