Multinucleon transfer experimental campaigns at GSI — •Ali Mollaebrahimi for the Super-FRS Experiment Collaboration collaboration — FAIR facility, Darmstadt, Germany — GSI facility, Darmstadt, Germany

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 and more efficient pathway to reach this region.

The Super-FRS experiment collaboration is performing MNT experiments at GSI using beams at near Coulomb barrier energies. This is performed with primary and secondary slowed-down relativistic beams at the FRS with the FRS Ion Catcher [1] and with primary beams at the UNILAC. The ultimate goal of the MNT program is to conduct future experiments at Super-FRS at FAIR. This contribution will present the plans and preliminary results obtained with ²³⁸U beam and the first test with ²³⁶U secondary beam on a Bi target and identification via mass measurements at the FRS Ion Catcher; plus general description of experiments with α-spectroscopy and TOF-ΔE-E methods after the UNILAC.
