Description
A deeper understanding of nucleon-induced reactions remains essential for nuclear theory as for applications in nuclear data. Several approaches have been developed in the last decades to correctly describe cross-sections for light particle emission, but it is still not possible to predict them for any nucleus in an arbitrary energy range with reasonable accuracy for practical applications. On the other hand, the nuclear data cycle strongly relies on experimental measurements, more abundant for energies up to 14 MeV due to historical limitations. Therefore, providing new data for higher energies remains as a goal of great interest.
Particles emitted from nucleon induced reactions with energies above 14 MeV can be described by the pre-equilibrium process, which considers multiple nucleon-nucleon interactions within the nucleus, leading to particle emission prior to statistical equilibrium. Structure effects are gradually “washed out” for higher energies. Such models are implemented in codes for calculating double differential cross-sections for different nuclei, such as TALYS [1], and uses experimental data as an input for correctly choosing its free parameters.
In this contribution, we report on the status of a series of experiments dedicated to measure the production cross-sections for the emission of light-ions in neutron-induced reactions. Those experiments have been carried out in the white neutron beam of the Neutrons for Science (NFS) facility, at GANIL (France), and within the framework of a collaboration between Uppsala University, GANIL, and the UK Atomic Energy Agency.
