摘要
Methods for measuring the layer-by-layer profiles of hydrogen in structural materials based on interpretation of the energy spectra of electrons reflected within a given spatial angle are discussed. Elastically reflected spectroscopy makes it possible to determine the hydrogen isotope content, but its implementation requires an energy resolution on the order of 1 eV. In the experimental implementation of the method based on analysis of the domelike part of the spectrum of reflected electrons, the required energy resolution of an analyzer is about 1%. Such a level of resolution makes it possible to measure the spectrum for several seconds. The possibilities of this method are illustrated with the use of hydrocarbon coatings.
