Fission-fragment total kinetic energy and mass yields for neutron-induced fission of U-235 and U-238 with E-n=200 keV-30 MeV

The average Total Kinetic Energy ((TKE) over bar) release and fission-fragment yields in neutron-induced fission of U-235 and U-238 was measured using a Frisch-gridded ionization chamber. These observables are important nuclear data quantites that are relevant to applications and for informing the next generation of fission models. The measurements were performed a the Los Alamos Neutron Science Center and cover E-n = 200 keV - 30MeV. The double-energy (2E) method was used to determine the fission-fragment yields and two methods of correcting for prompt-neutron emission were explored. The results of this study are correlated mass and (TKE) over bar data.
