“…The obtained value of T c complements existing data on its dependence on the energy of an incident nucleus, confirming the T c rise in the energy range from 1 to 3.2 GeV/nucleon. Together with the new data from the FODS experiment [29] at an energy of 19.6 GeV/nucleon [28] our result indicates the independence of the T c parameter for projectile energies above 3.2 GeV/nucleon. This energy dependence is like well measured in proton-nucleus collisions in the energy range from 0.7 to 400 GeV.…”

“…After the end of the intranuclear cascade, the excited nuclear matter disintegrates into prefragments, in which the total energy is statistically distributed between all possible combinations of fragments and particles. Wherein the distribution 6 GeV/nucleon) has been recently made at the FODS setup at IHEP [28,29] in C + Cinteractions at 0 • . With the consent of this group, we used this data to extract the cumulative temperature and obtained T c = 48.4 ± 0.7 MeV.…”

In the FRAGM experiment at the heavy-ion accelerator$$-$$accumulator complex ITEP$$-$$TWA, yields of cumulative charged $$\pi$$ mesons have been measured in a fragmentation of carbon ions with the energy of 3.2 GeV/nucleon on a beryllium target. The momentum spectra of $$\pi$$ mesons cover four orders of the invariant cross section magnitude. They demonstrate the exponential fall with increasing energy. The measured inverse slope parameter is compared with similar measurements in nucleon–nucleus interactions and ion–ion collisions at lower energies. The energy dependence of the ratio of the yields of negative to positive $$\pi$$ mesons is presented. This dependence is discussed in a connection with Coulomb and isotopic effects. The obtained data are compared with predictions of several ion–ion interaction models.
