Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Inelastic neutron scattering techniques are introduced here as one of the most important experimental techniques
in the investigation of collective excitations in fluids (liquids and compressed gases) and amorphous
solids. The correlation functions involved, the spectra of which are determined in inelastic neutron scattering
experiments, the dispersion relations of the collective excitations and how they are obtained from the measured
spectra and finally two of the most often used instrumental techniques are briefly discussed.
Методику непружнього розсiяння нейтронiв представлено тут як одну з найважливiших експериментальних методик для дослiдження колективних збуджень у плинах (рiдинах та стиснутих газах) та аморфних твердих тiлах. Коротко обговорюються вiдповiднi кореляцiйнi функцiї, спектри яких визначаються в експериментах по непружньому розсiянню нейтронiв, дисперсiйнi спiввiдношення для колективних збуджень та як вони можуть бути отриманi з вимiрюваних спектрiв, а також – двi з найбiльш часто використовуваних методик.
