CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe aim of this contribution is to present complementary results obtained by Thermal Restraint (TR) and Resolution Elastic Neutron Scattering (RENS) approaches. More specically, it is shown that the measured elastic scattering law as a function of temperature and of the logarithm of the instrumental energy of resolution give information on the system thermal response and on the system relaxation time. The RENS approach is tested numerically, taking into account a Gaussian resolution function and a Lorentzian scattering law, and experimentally by integrated EINS versus temperature (TR) and QENS measurements on three homologous disaccharide/water mixtures showing dierent relaxation times.
