PHASE-STRUCTURE OF SELF-SIMILAR MULTIPARTICLE SYSTEMS AND EXPERIMENTAL-DETERMINATION OF INTERMITTENCY PARAMETERS

In view of the possibility that self-similar multiparticle systems may exist in different phases, we investigate the structure of these phases using the random cascade model. It is shown that one phase ("liquid") is populated by many relatively small fluctuations, whereas the other one ("dust") consists of a few very large ones. The "dust" is suspended in the "liquid" like a colloid. Because of the rarity of "dust particles", the measurements of intermittency parameters including the dust phase require unusually large statistics, particularly at high resolution. © 1990.
