Parameter Optimization of FREYA for Spontaneous Fission

ORAL

Abstract

The fast event-by-event fission code FREYA (Fission Reaction Event Yield Algorithm generates large samples of complete fission events. FREYA employs only a few physics-based parameters. We discuss recent results on optimization of these parameters and compare results with the optimized parameters to available data on prompt neutron and photon emission.
