We measure cross sections for residual nuclide formation in the mass range 7 ≤ A ≤ 96 caused by bombardment with protons and deuterons of 3.65 GeV/nucleon energy of enriched tin isotopes ( 112 Sn, 118 Sn, 120 Sn, 124 Sn). The experimental data are compared with calculations by the codes FLUKA, LAHET, CEM03, and LAQGSM03. Scaling behavior is observed for the whole mass region of residual nuclei, showing a possible multifragmentation mechanism for the formation of light products (7 ≤ A ≤ 30). Our analysis of the isoscaling dependence also shows a possible contribution of multifragmentation to the production of heavier nuclides, in the mass region 40 ≤ A ≤ 80.

The recoil properties of fragments produced by the interaction of 4.4 GeV deuteron with 197 Au target have been studied. New experimental data on recoil properties for 90 nuclei, varying from 24 Na to 198 Au, were obtained. The technique applied was the thick-target thick-catcher and induced activity method. The deuteron beam was obtained from the Nuclotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR), Dubna. The experimental data were analyzed on the basis of the standard two-step vector model formalism. From this analysis we could find evidence to support the existence of several different mechanisms, such as spallation, fission and fragmentation, in the reaction investigated. Fission contributed appreciably to the formation of products in the mass region of 65 ≤ A ≤ 120. The kinematic characteristics of residual nuclei formed in the present deuteron-induced reaction have been compared to those from proton-induced reactions with gold target.

The recoil properties of the product nuclei from the interaction of 3.65 GeV/nucleon protons and deuterons from the Nuclotron and Synchrophasotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR) at Dubna with a 118 Sn target have been studied using catcher foils. The experimental data were analyzed using the mathematical formalism of the standard two-step vector model. The results for protons are compared with those for deuterons. Our experimental results were compared to three different Los Alamos versions of the Quark-Gluon String Model (LAQGSM). The forward velocity v and the recoil nuclei kinetic energy increases linearly with increasing mass loss of the target ∆A, but seems to change its slope at around ∆A = 60. It seems that light-and medium-mass products are produced partly by a fragmentation mechanism.
