Developed at Los Alamos National Laboratory, CGMF is an open-source code used for determining prompt neutron and gamma-ray properties, including correlations between different observables. Based on a Monte-Carlo implementation of Hauser-Feshbach statistical model of neutron-induced reactions, the code simulates in competition the neutron and gamma emissions from fission fragments, which are...

We reinvestigated the neutron multiplicity yields of Ba-Mo, Ce-Zr, Te-Pd, and Nd-Sr from the spontaneous fission of $^{252}$Cf; by (i) using both $\gamma$-$\gamma$-$\gamma$-$\gamma$ and $\gamma$-$\gamma$-$\gamma$ coincidence data, (ii) using up to date level scheme structures, and (iii) cross-checking analogous energy transitions in multiple isotopes, we have achieved higher precision than...
Measurements of independent isotopic fission yields (IIFYs) provide access to the probability distribution of fission products, which contribute to understanding nuclear fission in more depth than mass yield distributions. Better knowledge of fission has wide implications, including the abundance of elements through nucleosynthesis, nuclear structure and reactions, and nuclear waste management...

The last major evaluation of fission product yields from actinides was a compendium put together in 1994. It forms the basis for the current fission product yields for various incident neutron energies on actinide isotopes (ie: U235, U238). In 2010, the Godiva critical assembly was re-commissioned by the Department of Energy, led by Los Alamos National Laboratory, at the National Criticality...
