abstract = {Real-time inelastic neutron scattering has been used to
study the kinetics of the demixing process in AgBr-NaBr
mixed single crystals. The variation of transverse acoustic
phonon spectra provides most direct information about the
microscopic non-equilibrium behaviour. The phase separation
is monitored by a well defined splitting of phonon peaks
that reflects the different dynamical behaviours of the
constituents. As a function of temperature, time evolution
of the phonon spectra changes drastically, thus proving
unambiguously that the demixing process is dominated by
nucleation in the high-temperature regime and by
concentration fluctuations at low temperatures.},
