Abstract
The behavior of the inclusive cross sections for the cumulative production of π ± mesons and protons in pA, DA, and 4HeA interactions is studied versus the atomic mass number of fragmenting nuclei. The primary-beam momenta were 4.5 GeV/c per nucleon. Secondary pions and protons were recorded with a fixed momentum of 0.5 GeV/c at an angle of 120°. Specifically, the experiment explored the fragmentation of D, He, 6Li, 7Li, C, Si, 58Ni, 64Ni, 64Zn, 114Sn, 124Sn, and Pb nuclei. The energy spectra of π + and π − mesons and protons with momenta in the range 0.3–0.7 GeV/c (the emission angle being 120°) were measured in an 8.9-GeV/c proton beam for Ni, Zn, and Sn isotopes. The special features in the behavior of the cross sections are found and discussed, and a comparison is drawn with the results of other studies.
