This paper deals with the interactions of 12">12C-nucleus with the nuclear emulsion at 4.5">A">GeV/c, focused on distributions of multiplicity and the variation of the average multiplicities for secondary charged particles (black, gray, shower, and heavy particles) for the events released from these interactions. These averages have been calculated based on a model of modified cascade evaporation. A comparison has been ... إقراء المزيد
