The study and calculation of cross sections for reactions between light nuclei, such as D+D and D+T, are of interest both in astrophysics, for understanding primordial nucleosynthesis, and in fusion energy production (ITER, etc.).
Current international nuclear data libraries (such as ENDFBVIII, JENDL-5, or CENDL-3) are still relatively limited in their description of some of these reactions, particularly those induced by charged particles.
Furthermore, it is rare to have access to the uncertainties associated with cross sections.

The goal of this postdoctoral position is to reevaluate some reactions using the R-matrix approach. Initially, we will focus on D+D and D+T reactions in order to produce evaluated files containing both cross sections and the associated uncertainties.
Furthermore, the traditional R-matrix approach generally deals with entry and exit channels involving only two bodies. However, due to the very nature of light nuclei, channels involving more bodies can easily open up. We therefore plan to implement extensions of this approach to study reactions that include three-body exit channels.
