Power Moments and Scaling Properties of Nuclear Emulsion Data

Abstract

Various features of the charge yield in heavy ion collisions are studied. Considered here are the nuclear emulsion data of ${}^{84}$Kr, ${}^{131}$Xe, ${}^{197}$Au, ${}^{238}$U in the energy range of 1 GeV/A. Mean charge yields and multiplicity distribution of these data indicate that the nuclear fragmentation at this energy is a multiprocess phenomena. Power moments of the charge distribution exhibit a scale invariance. While small nuclei (Kr and Xe) show a nuclear size dependence, large nuclei (Au and U) exhibit scale independence in their charge distribution.
