Abstract
A study is made of the characteristic features of changes in electron spectra behind two-layer barriers for small variations in the thickness of the layers. It is shown that the high-energy region of the spectrum of electrons emerging from the barrier into a small solid angle in the forward direction contains the most information about the barrier thickness and the new spectrum characteristics introduced make it possible, in transilluminating two-layer objects with a beam of fast monoenergetic electrons, to determine the layer which changes its thickness.
