Description
Studying exotic nuclei exhibiting an extreme ratio of neutrons to protons is one of the primary means for better understanding of fundamental nuclear properties, which is crucial to comprehend the formation and existence of heavy elements in our universe. Nevertheless, it is well understood that nuclei from certain regions on the chart of nuclei, e.g., neutron-rich actinides, will not be efficiently produced in commonly used fission and fragmentation production methods. The multinucleon transfer (MNT) reaction mechanism is considered the most promising pathway to reach this region. The MNT mechanism may also be more efficient for producing other heavy neutron-rich nuclei, e.g., N=126 nuclei relevant for the origin of the 3$^{rd}$ abundance peak in the r-process.
The Super-FRS experiment collaboration started performing MNT experiments using both stable and secondary beams at FRS with the FRS Ion Catcher at GSI Helmholtz Centre for Heavy Ion Research in Germany in the summer of 2024 [1]. The program is also developing toward the preparation for future experiments in Super-FRS at the under-construction FAIR facility. This contribution will present the plans and preliminary results of the MNT experiments performed with $^{238}$U stable beams and the first test with $^{236}$U secondary beams.
