  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.
