Accurate measurements of structure factors of liquids by slow-neutron spectrometry

  • Published:
Il Nuovo Cimento B (1965-1970)

Summary

With reference to the limits of validity of the static approximation, the use of the methods of conventional and « quasi-elastic » diffraction of slow neutrons for an accurate determination of the structure factor of liquids is discussed. Some criteria are suggested, which should be useful for extracting from a diffraction pattern the structure factor. Experimental tests supporting our remarks are also presented.

Riassunto

Con riferimento ai limiti di validità dell’approssimazione statica, viene discusso l’impiego dei metodi della diffrazione convenzionale e della diffrazione « quasi-elastica » di neutroni lenti per una accurata determinazione del fattore di struttura dei liquidi. Vengono suggeriti alcuni criteri che potrebbero essere utilmente adottati per estrarre il fattore di struttura a partire da un diagramma di diffrazione. Vengono infine presentati alcuni risultati sperimentali che convalidano le considerazioni svolte.
