Inelastic interactions of protons with photoemulsion nuclei at 4·5 GeV/c

In inelastic collisions of protons with photoemulsion nuclei at 4·5 GeV/c, data have been obtained on multiplicity of shower particles, energy spectrum of fast secondary protons with (2·5±0·1) GeV average energy, and energy spectrum of produced charged pions with (640±±50) MeV average energy. The multiplicity, angular distributions, and energy of particles arising from splitting target-nuclei are also determined: the proton spectrum is approximated by the power dependenceE-γ withγ=1·4±0·1. The distribution of protons andπ-mesons over rapiditiesy=0·5 In[(E+p)/(E−p)] have been obtained. The average multiplicity for secondary particles coincide with the predicted values given by the cascade-evaporation model.
