Title: Implementing and testing theoretical fission fragment yields in a Hauser-Feshbach statistical decay framework

Abstract

Here, we implement fission fragment yields, calculated using Brownian shape-motion on a macroscopic-microscopic potential energy surface in six dimensions, into the Hauser-Feshbach statistical decay code CGMF. This combination allows us to test the impact of utilizing theoretically-calculated fission fragment yields on the subsequent prompt neutron and γ-ray emission. We draw connections between the fragment yields and the total kinetic energy TKE of the fission fragments and demonstrate that the use of calculated yields can introduce a difference in the $$\langle$$TKE$$\rangle$$ and, thus, the prompt neutron multiplicity v, as compared with experimental fragment yields. We deduce the uncertainty on the $$\langle$$TKE$$\rangle$$ and v from this procedure and identify possible applications.
