Relaxation and consolidation processes in solids (stress relaxation, physical aging) exhibit a number of similarities, especially with regard to the kinetics involved. In this paper, we derive a kinetic formula representing the time-domain equivalent of a Bose-Einstein (BE) distribution. The approach is based on the master equation supplemented with a BE enhancement factor. The plausibility of the underlying physical mechanism is discussed, especially with regard to the clustering of the elementary transitions involved in such a process.
