We compute the multifractal moments Gq in terms of a new scaled variable X suggested by Bialas and Gazdzicki to study the dynamical fluctuations of particles produced in the interactions of Au197 at 10.6A GeV with nuclear emulsion. An asymptotic power-law dependence of the moments on the bin size δX has been observed in pseudorapidity (η), azimuthal (φ), and η-φ phase spaces. The dynamical values of the generalized dimensions are determined in all the phase spaces. The dynamical properties of the produced particles are mapped onto smooth multifractal spectra f(Δαq) by excluding the statistical contribution. The Au197 results are compared with a Si28 ion at 14.5A GeV and a S32 beam at 200A GeV.
