HauserFeshbach fission fragment deexcitation with calculated macroscopicmicroscopic mass yields
Abstract
The HauserFeshbach statistical model is applied to the deexcitation of primary fission fragments using input mass yields calculated with macroscopicmicroscopic models of the potential energy surface. We test the sensitivity of the prompt fission observables to the input mass yields for two important reactions, ^{235}U (n _{th}, f) and ^{239}Pu (n _{th}, f) , for which good experimental data exist. General traits of the mass yields, such as the location of the peaks and their widths, can impact both the prompt neutron and γray multiplicities, as well as their spectra. Specifically, we use several mass yields to determine a linear correlation between the calculated prompt neutron multiplicity $$\bar{v}$$ and the average heavyfragment mass $$\langle$$A _{h}$$\rangle$$ of the input mass yields ∂$$\bar{v}$$/∂ $$\langle$$A _{h}$$\rangle$$ = ± 0.1 (n / f )/u . The mass peak width influences the correlation between the total kinetic energy of the fission fragments and the total number of prompt neutrons emitted, $$\bar{v}_T$$ ( TKE ) . Finally, typical biases on prompt particle observables from using calculated mass yields instead of experimental ones are δ$$\bar{v}$$ = 4 % for the average prompt neutron multiplicity, δ$$\overline{M}_γ$$ = 1% for the average prompt γray multiplicity, δ$$\bar{ε}$$ $$LAB\atop{n}$$ = 1 % for the average outgoing neutron energy, δ$$\bar{ε}_γ$$ = 1 % for the average γray energy, and δ $$\langle$$TKE$$\rangle$$ = 0.4 % for the average total kinetic energy of the fission fragments.
