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

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 gamma-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 (TKE) and, thus, the prompt neutron multiplicity (nu) over bar, as compared with experimental fragment yields. We deduce the uncertainty on the (TKE) and (nu) over bar, from this procedure and identity possible applications.
