Abstract: (APS)
The weak nonexponential relaxation ∝t−a′ recently found in computer experiments on the phase separation of alloys is explained in terms of a cluster reaction and diffusion process. The nonlinear features of this process can be accounted for by a time-dependent diffusion constant. Estimates for the resulting exponents [a′=1(3+d)] are consistent with the computer simulations. The experimental observability of this slowing down is discussed.References(22)
