Abstract
The SPALADIN experiment using the inverse-kinematics technique where the heavy-ion beam is sent onto a liquid-hydrogen target has been carried out at GSI (Darmstadt, Germany) in order to study the spallation of Fe-56. On an event-by-event basis, spallation residues, light-charged fragments and neutrons have been detected in coincidence. The set-up is based on a large aperture magnet (ALADiN) equipped with a time-projection chamber (TPC), a hodoscope and a high-efficiency neutron detector. The combination of the inverse kinematics and of the acceptance of the set-up focuses the measurement on the low centre-of-mass energy fragments of the reaction essentially originating from the de-excitation of the prefragment formed at the end of the intranuclear cascade. Data taken at 1 GeV per nucleon have been analysed. Preliminary results on coincidence observables are shown and compared to theoretical calculations. We emphasize on the identification of different types of multi-fragment final states which correspond to different decay channels and allow to probe different decay mechanisms.
