Evaporation and pre-equilibrium emission in GeV p-induced spallation-fragmentation reactions — •Frank Goldenbaum — for the PISA collaboration, Forschungszentrum Jülich GmbH, Institut für Kernphysik, Jülich, Deutschland

The emphasis will be on the description of nuclear data taken by the PISA (Proton Induced SpAllation) experiment at the Cooler Synchrotron in Juelich, Germany. The typical energy range of incident protons is 150 MeV-2.5 GeV with luminosities for the internal experiment PISA up to 6× 10³⁴ cm⁻²s⁻¹. The goal of the experiment was to improve nuclear data evaluated files and models which involves sensitivity analysis and validation of simulation tools, nuclear data libraries evaluation at low and medium energies, and high energy (≥200 MeV) experiments and modeling. In the present contibution the focus is on high energy experiments and modeling and will cover the investigation of: i) pA (spallation-fragmentation) reactions in the GeV regime ii) data measured from exclusive experiments for testing, validating and developing theoretical models iii) double differential cross sections (DDXS) of light charged particles (LCP=p,d,t,3He,4He,...) and intermediate mass fragments (IMFs, Z≤ 16) in spallation and fragmentation p-induced reactions (C to Au), and iv) reaction mechanism of pN reactions, origin of pre-equilibrium, evaporation and fragmentation processes.
