Fission studies in inverse kinematics and associated development of new time-of-flight

Abstract

This work focuses on the proton- and deuteron-induced fission of 181Ta and 208Pb measured in experiments performed at GSI (Helmholtzzentrum für Schwerionenforschung - Darmstadt Alemania) using the inverse kinematics technique. According to this scope, a dedicated experimental setup with high acceptance and efficiency for fission measurements is used. The obtained results allow to improve the knowledge about fission cross sections of relevance for the construction of spallation neutron sources useful in many technology areas. In addition, reaction codes based on models describing the fission process at high excitation energies are also investigated and benchmarked by comparison to our experimental data. The experimental part is completed with the R and D of Resistive Plate Chambers (RPC) for the construction of a time-of-flight detector for the R3B experiment in the forthcoming FAIR facility (Darmstadt).
