Abstract
In the present work we have studied single crystals of natural diamonds, diamonds synthesized in the Ni-Mn-C and Ni-Mn-C+B growth systems as well as diamonds grown by the temperature gradient method. Experimental study of the intensity profiles of the Kossel lines have shown that for the equivalent crystallographic directions, the halfwidths of extinction lines differ and the bifurcation of Kα1 and Kα2 lines appear from some planes of the lattice. The use of the dynamic theory of X-ray scattering for a case of the periodic strain of the diamond lattice has allowed us to substantiate theoretical profiles of the Kossel lines that qualitatively coincide with experimental data.
