The experimental data on nuclear emulsion at 800 GeV have been analysed to study the nuclear effects and intermittency in two dimensions in terms of the factorial moments. The fractal dimension and the phase structure function are found to be in agreement with the theoretical predictions. We also evaluate slope ratios in one dimension for the cosmic ray data and in two dimensions for the 800 GeV data, for different reactions and different primary energies. Our results exhibit universality of the intermittent behaviour in the two data sets.
