The quasielastic neutron scattering experiments on liquid sodium (at T = 378, 573, and 693 K) and sodiumhydrogen melt (T = 693 K, hydrogen concentration ∼ 0.4 at %) were performed with the DIN-2PI time-of-flight spectrometer. The characteristics of

The temperature dependence of the self-diffusion coefficient of liquid lithium in the temperature range of 500–830 K has been investigated using coherent quasi-elastic neutron scattering. Good agreement with the results obtained from incoherent qua
