RESEARCH OF STRUCTURAL DYNAMIC PROPERTIES OF SUBSTANCE Russian patent published in 2008 - IPC G01N23/02 

FIELD: physics.

SUBSTANCE: substance sample under investigation is exposed to a polarised neutron cluster with polarisation vector precesses in magnetic fields before and after the sample, and cosine Fourier transform of cumulative curve is measured by the energy spectrum of polarisation neutrons and applied in analysis of structural dynamic properties related to the even part of its excitement frequency spectrum. At that, at the precession field output a field is created to rotate polarisation around an axis perpendicular to the axes of previous rotation, additionally sine Fourier transform of cumulative curve is measured by the energy spectrum of polarisation neutrons, uneven part of excitement frequency spectrum of the sample is defined to obtain complete information on structural dynamic properties of a substance on the basis of even and uneven parts of its excitement frequency spectrum.

EFFECT: support of complete analysis of structural dynamic properties of a substance.
