Researsh of altitude of potential barrier at the metal-vacuum interface by the diffraction method

Abstract

The paper considers the problem of diffraction at normal incidence of a monochromatic beam of photons on a grating of thin metal strips. Quantum-mechanical approach is used to describe the phenomenon of diffraction of particles. Based on the elastic interaction of photons with electrons, that is in the strip and carries a one-dimensional movement in the potential pit with barriers of finite height, relations for discrete values of angles, at which the diffraction peaks should be observed, were obtained in the first approximation. The equations obtained in this work are the same in the case of small angles of diffraction as the known in the scientific literature expressions that determine the position of the diffraction peaks in the case of diffraction of light at a diffraction grating surface. The relation to determine the height of the potential barrier at the metal – vacuum interface was obtained.
