Predictions for the synthesis of new superheavy nuclei with a ²⁵²Cf target*

Abstract The isotope produced at Oak Ridge National Laboratory is a promising target material for the synthesis of new superheavy nuclei through fusion reaction experiments. Within the framework of the dinuclear system model, reaction systems with the target and , , , , , and projectiles are investigated for the synthesis of the new isotopes , , , , , and . The decreasing trend of maximal evaporation residue cross sections with the increasing proton number of the compound nucleus is discussed in the capture, fusion, and survival stages. Additionally, radioactive beam-induced reactions based on the target are investigated to reach the predicted neutron shell closure N = 184, with the maximal evaporation residue cross section predicted to be 21 fb for synthesizing . The predicted results fall below the current detection limitation, indicating the necessity for advancement in both accelerator and detection techniques, as well as exploration of alternative reaction mechanisms.
