Abstract
The processes of generating phonons and electronic excitations by an oriented quantum particle in a crystal are considered. The probabilities of the excitation of phonons and plasmons are calculated. A theory of crystal excitation by a channeled particle with simultaneous photon emission is developed. The probability of a process with the fast particle transitioning into a virtual state after emitting a plasmon, followed by photon emission, is determined. The probability of the process involving photon and plasmon emission is of the same order of magnitude as the probability of the standard process with photon emission alone. The possibility of experimentally detecting the effect is assessed. It is demonstrated that all features of electronic and phonon excitations manifest as components of the radiation spectrum from a fast oriented charged particle in a crystal.
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.
