Similarity in the distributions over the multitudes of secondary negative particles formed in collisions of p, d, 4He and 12C with 12C and 181Ta at 4.2 GeV/c.nucl

The distributions over the multitudes of π--mesons formed in inelastic collisions of protons and nuclei of deuterium, helium and carbon with nuclei of tantalum and carbon at initial momentum of 4.2 GeV/c.nucl. are analysed. The experimental data are obtained using a two-meter long propane bubble chamber. All secondary negative charged particles except identified electrons are assumed to be π--mesons. The analysis is performed using a modified KHO scaling, verifying again the independence of topological cross-sections of n-particle inclusive processes on the energy. The momentum distribution ratio over the multitudes is found to be constant at a value of the parameter α=-0.6. The behaviour of the distributions in terms of the modified KH0 scaling is obtained to be universal for π--mesons formed in internuclear collisions as well as in p-p interactions at momentum higher than 60 GeV/c
