Proton- and Deuteron-Induced Reactions on ⁹³Zr in Inverse Kinematics

Nuclear reactions occurring at energies of a few tens of MeV per nucleon (MeV/u) are primarily influenced by compound and pre-equilibrium processes. Unlike direct reactions, these processes involve the dissipation of the projectile’s kinetic energy into the target nucleus. Several factors, such as the initial energy and level densities of the nuclides involved in the reaction, can influence the cross sections leading to the formation of final nuclei. The reaction mechanism becomes more complex when considering deuteron-induced reactions, as the loosely bound nature of the deuteron increases the possibility of its break-up near the target. In this study, we conducted measurements of the cross sections for the reactions ⁹³Zr + p and ⁹³Zr + d at approximately 28 MeV/u, employing inverse kinematics with the BigRIPS-OEDO beamline and SHARAQ spectrometer. These measurements were part of the experimental campaign conducted by the ImPACT17-02-01 collaboration. To analyze our experimental results, we compared the production cross sections of each isotope with the theoretical estimations obtained from TALYS and DEURACS codes. Additionally, we examined previous measurements conducted at higher energies. In this presentation, we will provide a comprehensive overview of the experimental methodology, present the results obtained for the reactions ⁹³Zr + p and ⁹³Zr + d, and discuss potential interpretations of the results by comparing them with the theoretical calculations.
