ABSTRACT:

Machine learning methods are used to analyze systematic trends in nuclear reaction cross section evaluations over the nuclear landscape. We employ a system of multiple generative adversarial neural networks to learn how a cross section changes when proton- and/or neutron-number change. The model uses an ensemble of neural networks to predict cross sections, which helps to identify anomalies in libraries and to make extrapolations to where experiments cannot be done. This work is the foundation for a larger system that can incorporate correlations between reaction channels and enhance our understanding of trends in reaction data.
