Methods of Measuring Physical Characteristics of Partial Components of   Multicomponent Samples
  Consideration is given to the methods of gaining experimental data on the substances which constitute a part of multicomponent samples to be measured. The methods are applicable to the samples comprising an arbitrary number of components; their use is not restricted to single-type experiments only. The application of the methods is demonstrated with an example of obtaining the spectra of electrons scattered by 6Li and 7Li nuclei, which were measured from two targets having different isotopic compositions. As a result of the proposed methods, spectra were obtained for the electrons scattered by the nuclei of each of the constituent isotopes, as if the experiment were made on isotopically pure targets.
