Isoeffect in reactions on enriched tin isotopes with 12C ions at energy

Interaction of 12C ions with nuclei of enriched tin isotopes at an energy of 2.2 GeV per nucleon

“…In the mass region of 40 < A < 60, the cross section σ А undergoes virtually no change. In this region, the product-formation process may receive contributions not only from spallation but also from multifragmentation and fission [11][12][13][14][15] (yet, the contribution of fission is relatively small in the case of tin targets [16]). In the region of A < 40, there may arise fragmentation and multifragmentation products.…”

Symmetry energy and the isoscaling in reactions on enriched tin isotopes

“…In our previous studies of the nuclear reactions induced by protons with energies of 0.66 and 8.1, 3.65 GeV, deuterons (E=3.65 AGeV) and 12 C ions (E=2.2 A GeV) оn targets of tin isotopes the isoscaling behavior was shown using the induced activity method [17,18] and it was described in terms of the third component of the fragment isospin t 3 =(N-Z)/2. The isotopic ratio of the product formation cross sections has been considered in the following form:…”

“…It is possible to calculate values of ρ/ρ 0 and T for heavier product nuclei produced in proton and deuteron induced reaction with 3.65 GeV/nucleon incident energy using above mentioned procedure. The values of Ē* have been taken from [24] and isoscaling parameter α=B/2 from [18]. Obtained results are given in Tab.2,3.…”

“…The isotopic effect was observed by Bogatin et al for reactions induced by protons, deuterons and α particles of incident energies between 660 MeV and 15.3 GeV on 112,124 Sn targets [12][13][14]. The dependence of yields of photonuclear reactions and nucleon-nuclear reactions on values of third projection of isospin of target and product nuclei was investigated in our previous works [15][16][17][18].…”
