In the framework of a dynamical multifragmentation model we investigate the fragmentation of expanding nuclear systems. We find that the stable fragment mass multiplicity distribution differs (in some cases essentially) from the cluster distribution in the statistical equilibrium investigated so far. We especially investigate the pure power-law ansatz of the equilibrium distribution and find that in certain cases the fragmentation process leads to final mass distributions again in the form of a power-law, however, with an effective exponent.
