Spallation-induced fission reactions, in combination with state-of-the-art dynamical calculations, provide a robust framework for studying the nuclear dissipation mechanism matter over wide range of deformations. Experimental datasets neutron- and proton-induced fission, accumulated last decades, cover nuclei from pre-actinide to actinide region. In this work, these are used benchmark Li\`ege intranuclear cascade model INCL++ integrated ABLA++ de-excitation code, which has been improved by...
The accuracy of reaction theories used to extract properties exotic nuclei from scattering experiments is often unknown or not quantified, but utmost importance when, e.g., constraining the equation state asymmetric nuclear matter observables as neutron-skin thickness. In order test Glauber multiple-scattering model, total interaction cross section on carbon targets was measured at initial beam energies 400, 550, 650, 800, and 1000 MeV/nucleon. measurements were performed during first...
In the last decades, measurements of spallation, fragmentation and Coulex induced fission reactions in inverse kinematics have provided valuable data to accurately investigate dynamics nuclear structure at large deformations a variety stable non-stable heavy nuclei. To go step further, we propose now induce by use quasi-free (p,2p) scattering kinematics, which allows us reconstruct excitation energy compound fissioning system using four-momenta two outgoing protons. Therefore, this new...

Lihtar et al.The Coulomb excitation of 124,128,130,132,134 Sn isotopes in the electric field a Pb target have been studied using R 3 B setup as part FAIR Phase-0 program.The experiment was motivated by possibility nuclear dipole response to infer valuable information on slope symmetry energy equation state.Measurements were performed inverse kinematics at relativistic energies 750 MeV/u and 904 MeV/u.The analysis method preliminary results for decay channel with single outgoing neutron...
A new experimental fission approach is presented in the context of R 3 B (Reactions with Relativistic Radioactive Beams) collaboration, at GSI/FAIR facility, which knockout reactions inverse kinematics are used to induce 238 U that will allow characterise excitation energy process and all products. The CALIFA (CALorimeter for In-Flight detection γ-rays high charged pArticles) calorimeter, a key part set-up, reconstruct momenta two protons from (p, 2p) reactions. Preliminary results show...
This work presents a systematic study of the properties (Light Output Non-Uniformity (LONU) and energy resolution) two CsI(Tl) scintillation units over span almost three years, under adverse conditions humidity temperature. These crystals are part CALIFA detector, highly segmented calorimeter spectrometer for γ rays light-charged particles, that is placed surrounding reaction target at Cave C, experimental cave R3B (Reactions with Radioactive Relativistic Beams) collaboration GSI-FAIR...
Despite the recent experimental and theoretical progress in investigation of nuclear fission process, a complete description still represents challenge physics because it is very complex dynamical whose involves coupling between intrinsic collective degrees freedom, as well different quantum-mechanical phenomena. To improve on existing data fission, we produce reactions heavy nuclei inverse kinematics by using quasi-free (p,2p) scattering, which induce through particle-hole excitations that...
Nuclear fission is a complex dynamical process, whose description involves the coupling between intrinsic and collective degrees of freedom, as well different quantum-mechanical phenomena. For this reason, to day it still lacks satisfactory complete microscopic description. In addition importance describing itself, studies r-process in astrophysics depend on observables constrain theoretical models that explain isotopic abundances Universe. To improve existing data, reactions heavy nuclei...
The experimental data collected during the S515 experiment performed by R 3 B collaboration at GSI/FAIR represent a great opportunity to investigate nucleon knockout reactions of exotic nuclei in region Sn using complete kinematics measurements. These cross sections can be used future quenching minority species (neutrons or protons) far from stability. Some arguments put forward are underestimation deeply bound nucleons, final state interactions role short-range correlations (SRC). Recently,...
