Event-by-Event Fission Modeling with
FREYA
R. Vogt, J. Randrup, J. T. Van Dyke, and L. A. Bernstein
1 Overview
Nuclear fission has made a significant impact on society even though the physical
mechanisms behind the process are still not understood in detail. While great strides
have been made in theoretical many-body calculations of fission, see e.g. the talks
by W. Younes and N. Schunck in these proceedings, a comprehensive model of the
phenomenon, including neutron and photon emission, based on these theories is
still in the future. There is thus a need for more phenomenological approaches that
can model complete fission events. Such codes implement a physically consistent
description of fission and allow studies of correlations among fragments, neutrons,
and photons with full kinematic information.
