Correlations of Prompt Fission Gamma Rays and Neutrons in Fission*

Experimental data obtained with The Detector for Advanced Neutron Capture Experiments (DANCE) and NEUANCE arrays will be presented from spontaneous fission Cf-252 and U-235. These arrays have been modeled in MCNP® and Geant4, with the aim of simulating fully correlated events of de-excitation following the fission reaction, in conjunction with the Cascading Gamma-ray Multiplicity code for Fission (CGMF). Results of simulations are compared to experimental data with the goal of constraining the parameters of the CGMF model.
