The A/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at SIS. A stable beam of (124)Sn and radioactive beams of (124)La and (107)Sn at 600 MeV per nucleon have been used in order to explore a wide range of isotopic compositions. Chemical freeze-out temperatures are found to be nearly invariant with respect to the A/Z of the produced spectator sources, consistent with predictions for expanded systems.

- The study investigates how 56Fe spallation occurs when it collides with hydrogen at high energy (1A GeV), utilizing the SPALADIN setup at GSI in a method called inverse kinematics.
- The research focuses on measuring the coincidence of low-energy light particles and fragments, which allows for a breakdown of the total reaction cross section into various deexcitation pathways.
- The findings indicate that among different deexcitation models tested, only the GEMINI model accurately explains the majority of the experimental results, suggesting that in this light system, multifragmentation may not be necessary to account for the observations.
