"Improved Uncertainty Estimates with R-Matrix Theory" by Daniel Odell

In order to develop reliable predictions, the need to prioritize the comprehensive uncertainty quantification of nuclear structure and reaction predictions has only become stronger over that past several years. In line with this broader effort, I will present the results of our recent work to apply R-matrix theory to low-energy, nuclear reactions with Bayesian methods. First, I will present our analysis of the t(d,n)⍺ reaction, the results of which provide a more accurate prediction of the S factor at solar energies. Second, I will discuss our ongoing efforts to resolve discrepancies between the analyses of 3He(⍺,𝛾) capture and 3He(⍺,⍺) scattering data. Finally, I will give a preview of where the tools we have developed to analyze the 3He-4He system are being applied.
