摘要

研究了氢离子在金属薄膜上掠掠散射时的电子交换。所研究的主要特征是屈服分数，即散射粒子（在考虑的情况下为H -）形成某种电荷状态的概率作为平行于样品表面的速度分量的函数。通过对波矢量空间中电子分布的分析，并应用公认的费米球位移模型，证明了负氢离子形成的概率对平行速度分量的依赖性是单调递减的。

Theoretical Study of Electron Exchange under Grazing Scattering on Thin Metal Films

Electron exchange during grazing scattering of hydrogen ions on thin metal films is considered. The main characteristic being studied is the yield fraction, that is, the probability of the formation of a certain charge state of a scattered particle (in the case under consideration, H^–) as a function of the velocity component parallel to the surface of the sample. Based on an analysis of the electron distribution in the space of wave vectors and the application of the generally accepted model of displacement of Fermi spheres, it was shown that the dependence of the probability of the formation of a negative hydrogen ion on the parallel velocity component should decrease monotonically.

期刊介绍： Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
