AbstractAbstract
[en] The problem of scattering of long-wave neutrons on the ion crystal lattice defects is solved in the harmonic approximation. The numerical calculations of the differential cross section of the neutron scattering on Cl vacancies in NaCl for the wavelength of 5.5; 7 and 9A are carried out for the case when the initial neutron momentum with the Λ wavelength is directed along the crystal axis (100). The whole region of static nonordering are taken into account in calculations. It is shown that except the region of small scattering angles, the behaviour of the cross section qualitatively coincides with the results of other authors and has a smooth character

AbstractAbstract
[en] On the example of tetrahedral interstitial in AHC it is shown,that the presence of interstitial, producing lattice unsymmetrical distortions, in fcc-lattice in diffuse near-Bragg scattering leads to the appearance of the member, which does not depend on the momentum transmitted, apart from normal Huang scattering. Lattice distortion is considered on the basis of lattice statics method. Calculations of distortion field, produced by U1-centre in KCl crystal, are carried out. Diffuse scattering on Frankel pairs is considered. It is shown, that near-Bragg diffuse scattering cross-section, averaged by Frenkel pairs configurations, where the vacancy and interstitial are placed at small distances, behaves as q-2, while averaging by pair configurations, which components are divided at distance of 10 inter-ion intervals, leads to q-4 cross-section dependence. Besides, in this case oscillations in scattering cross-section are obtained. Calculation of diffuse inter-Bragg scattering for KCl crystal with U1-centre and impure Frenkel pair is carried out
