Stopping of Fast Structural Ions in a Substance by Means of Excitation of Their Own Electrons

Resumo

The paper considers the theory of stopping of fast structural ions in a substance. Within the eikonal approximation, it develops a non-perturbative method for calculation of effective stopping of fast structural ions by means of excitation of their own electrons during collision with atoms. It shows that taking into account the interaction of atoms with the ion nucleus can make a considerable contribution into the value of the abovementioned effective stopping. It also examines the dependence of this contribution on the charge of the ion nucleus.
