Basic characteristics of nucleon interactions with light nuclei

Results of studying characteristics of the elementary act of interaction of particles of cosmic rays at energies of approximately 5 TeV with light substance and modern results, obtained on accelerators, are compared. Such interaction characteristics as Ksub(πsup(0)) multiplicity distribution gamma spectrum (scaling variable x distribution) and their angular distribution (rapidity distribution y) are considered. It is shown that the main characteristics of particle generation were obtained in cosmic rays earlier and at higher energies than at the accelerators. Some parameters (Ksub(πsup(0) distribution), correlation between Ksub(πsup(0)) and the energy spectrum and angular distribution of producting particles, multiparticle correlation in the fragmentation range) in the range >=1 TeV at accelerators have not been investigated up to now
