Zakopane 2026 Conference on Nuclear Physics

Charge-changing reactions (CCRs) at intermediate energies are an experimentally simple yet valuable tool for exploring the complex reaction mechanisms and exotic structures of rare isotopes.
Based on years of experimental studies at RIBLL2/HIRFL and FRS/GSI, our collaboration has investigated CCRs of more than 60 p-sd shell nuclei on various targets at approximately 300 and 900 MeV/nucleon.
Benefiting from this extensive and systematic dataset, we have demonstrated the indispensable role of charge-particle evaporation after neutron removals in CCR. We found an empirical yet robust method to infer the charge radii of isotopes of p-shell nuclei and suggest a heavy isotope target as the optimal choice. I will present some selected new results from our CCR studies and the perspective on using the Heavy-ion Accelerator Facility (HIAF).
