With the help of the scaled factorial moment method, we have studied the interaction of
24Mg-AgBr at the energy 4.5 A GeV. The whole process involves
determination of the intermittency index (aq), which
ultimately measures the variable lq (lq=(aq+1)/q). The
occurrence of a minimum in the variation of lq as a
function of q suggests a non-thermal phase transition and different regime of particle
production during the hadronisation process.
