【 摘 要 】

With the help of the scaled factorial moment method, we have studied the interaction of²⁴Mg-AgBr at the energy 4.5 A GeV. The whole process involvesdetermination of the intermittency index (a_q), whichultimately measures the variable l_q (l_q=(a_q+1)/q). Theoccurrence of a minimum in the variation of l_q as afunction of q suggests a non-thermal phase transition and different regime of particleproduction during the hadronisation process.
