The temperature dependence of the relaxation time distribution functiong(&tgr;)was obtained from a Tikhonov regularization analysis of dielectric loss data in the dipole glass DRADP-x(x=0.47).A crossover region of the relaxation dynamics was evidenced in the temperature region of40&hthinsp;K±2&hthinsp;Kfrom a distinct change in the shape ofg(&tgr;).We attempt to explain this crossover phenomenon in terms of a dynamically correlated domains (DCDs) model. ©2000 American Institute of Physics.
