K voprosu o kharakternikh tochkakh profilya dubletnikh Kα liniu pri rentgenostrukturom analyze polykristallov

The question of the relative arrangement of components of the Kα doublet line in the diffraction patterns of polycrystals is discussed. A characteristic point of the line profile is established, the abscissa of which is equal to two thirds of the doublet α₁–α₂ separation from the maximum of the Kα₁ component curve; its abscissa does not depend on component curve parameters. On annealed and cold-worked copper samples it is shown that the characteristic point abscissa may be used as a criterion for the correct resolution of the doublet line and for finding the influence of the different fine structure factors on the line profile.
