Recoil products from p+118Sn and d+118Sn at 3.65 GeV/A

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 118Sn target have been studied using catcher foils. The experimental data were analyzed using the mathematical formalism of the standard two-step vector model. The analysis of kinematical characteristics of the light and medium-mass reaction products confirmed the contribution of fragmentation (or multifragmentation) processes in the production of these nuclei. The comparison of the results for protons and deuterons was made. The longitudinal momenta transferred to the target in the interaction with protons and deuterons were similar and was shown to depend only on the velocity, but not on the mass of projectile. Three different Los Alamos versions of the quark—gluon-string model (LAQGSM) were used for the discussion of our experimental results.
