Multiplicities in ${}_{}{}^{16}{}_{}{}^{}\mathrm{induced}$ violent heavy-ion collisions from 5A to 2×${10}^5$A MeV

Target-fragment, shower-particle (meson), interacting-proton (36–400 MeV), and total multiplicities in ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$+Ag collisions from 5A MeV to 2×${10}^5$A MeV are studied. The target disintegration exhibits energy independence above 100A MeV even in the most central collisions. Above 5A GeV the energy dependences of the three different categories of particles are similar to those from proton-nucleus interactions. The absolute yield of target fragments is also the same while the yield of protons is twice as large and of shower particles 6–7 times larger in ${}_{}{}^{16}{}_{}{}^{}\mathrm{induced}$ central collisions as compared to p-nucleus reactions.
