Analysis of collective properties of secondary particles in CC interactions at 4.2 GeV/c x per nucleon

Collective properties of charged secondary particles produced in all and in multinucleon CC collisions at 4.2 GeV/c per nucleon are analysed. These are expressed in terms of sphericity, thrust, flatness, < Psub(out)sup(2) > and < Psub(in)sup(2) >. Production of secondary charged particles, collimated in the direction of colliding nuclei motion, is noticed. The experimental data are compared with the intranuclear cascade model predictions and with the calculations by the model assuming indepen-- dent nucleon-nuclear interactions. It is shown that collective properties of protons and compound particles (d, t, He) produced in multinucleon CC-collisions cannot be described by these models of noncollective type nucleus-nucleus interactions
