The dielectric theory of ion–matter interaction is extended to the case of excited swift ions to investigate possible influence of deformation (alignment) of their electron cloud on their stopping. Calculations are performed for the stopping effect

A computer simulation study of the transmission of low-energy antiprotons through a thin single crystal, along one of the axial directions, is reported. The angular distribution of the scattered antiprotons behind the crystal is analysed. As an examp

A detailed study of energy spectra (channeled fraction, most probable energy loss, shape of the spectra) of low energy antiprotons moving in a thin crystal, under axial channeling conditions is performed using a Monte Carlo computer simulation. The r

A detailed theoretical analysis of experimental energy spectra of axial-channeled protons transmitted through thin silicon targets is performed by Monte Carlo calculations. Energy spectra are calculated for 〈110〉, 〈111〉, and 〈112〉 channel

The charge asymmetry effects in the dependence of electronic energy loss on impact parameter are studied theoretically. Allowance for some corrections to the calculations made in terms of the first-order perturbation theory is shown to result in a de

The dependence of the electronic energy loss of antiprotons on the impact parameter has been studied theoretically. The differences in the energy losses of protons and antiprotons are discussed. The following Z13-corrections are taken into account: t

The local electron density approximation is used to calculate the position and value of the maximum in the proton stopping cross-section for gases and solids. The electron density of atoms in gases is calculated using the Hartree-Fock-Slater approxim
