The proposed project investigates multinucleon transfer reactions as a tool for synthesizing neutron-rich heavy nuclei, particularly near the neutron magic number 126 and in the actinide region. Utilizing state-of-the-art instrumentation and advanced capabilities of the PRISMA magnetic spectrometer, the AGATA gamma-ray tracking array, and the NOSE detector, we will conduct high-resolution measurements of mass (A), charge (Z), and energy distributions, and perform detailed gamma-ray spectroscopy of reaction products. By employing inverse kinematics and innovative triple coincidence techniques, we aim to directly detect both reaction partners for the first time with unprecedented resolution and quantify the effects of secondary processes such as neutron evaporation and fission on their survival probability. Additionally, in a new set of experiments we will explore a potential of using a broader range of detection angles and utilize reaccelerated radioactive beams for the first time with the magnetic spectrometer.The expected results of the proposed project are high-quality experimental data from several key experiments, providing new insights into nuclear reactions and structure of neutron-rich nuclei. These results will be presented at leading international conferences and published in top international journals, offering valuable benchmarks for theoretical models. Beyond its scientific contributions, the proposed project will establish a new heavy-ion physics group at RBI with extensive international research experience, that will establish new comprehensive approach to the study of reaction mechanisms and structure of neutron-rich heavy nuclei with the most-modern detection systems and techniques. This will strengthen Croatia’s position in the international research community and establish a foundation for long-term excellence in nuclear physics and related fields.
