Characteristics of Slow Particles in Hadron–Nucleus Interactions and Their Relation to the Models of High-Energy Interactions

摘要

Some characteristics of grey and black tracks (treated separately) produced in the interactions of high-energy hadrons with nuclei were investigated. Differences in the behaviour of these two groups of particles were shown. It has been concluded that one can use the number of grey tracks N_g as the good measure of the number of collisions of the primary particles inside the nucleus. Furthermore we compared the experimental dependence of normalized multiplicity R on the mean number of collisions v with theoretical predictions in an interval of ar u about twice as large as was possible in previous experiments (namely up to ar u pprox 7).
