The application of quantum-hydrodynamic methods for solving the problem of electron exchange between atomic particles and solid surfaces, and nanosystems has been examined. The derivation of a system of equations that is alternative to the nonstation

We have bombarded crystalline Si with high-energy (1.847 MeV/atom) atomic C+ and molecular C 2 + ions in 〈1 1 1〉, 〈1 0 0〉 and 〈2 1 1〉 axial channeling and in random directions to observe the effect of Coulomb explosion (CE) for the molecu

The backscattering energy spectra of protons have been measured with 650 keV/atom H þ ,H þ and H þ beams irradiating Si crystal in h 100 i and h 110 i directions. The Coulomb explosion of molecules on entering a crystal results in significant modi

The LPF approach of Lindhard and Scharff is generalized to describe on the same basis the impact parameter dependence of energy loss in ion–atom collision. To make this feasible the energy loss is represented as an integral of the local energy depo

The energy loss in the collision of a moving charged projectile with a free electron is described in a rigorous approach. The collision is treated as stationary scattering of an electron in the projectile Coulomb field. In the laboratory frame, the p

A method of calculation of Barkas correction to the charged particle energy loss for a given impact parameter, Δ E(b), is developed on the basis of local plasma approximation. It is shown that the anisotropy of wake potential should be accounted for

An efficient approach for the simulation of ion scattering from solids is proposed. For every encountered atom, we take multiple samples of its thermal displacements among those which result in scattering with high probability to finally reach the de

It is proved that the energy loss can be presented as a convolution of the electric force of the charged projectile with the density of the current induced in stopping media. This provides new possibilities in analysis and also in development of real
