A review of physics models in the LAHET trademark code

This paper discusses the various physics options available in LAHET, including the Bertini and ISABEL intranuclear cascade models, the multistage, multistep preequilibrium exciton model, and the level density parameter options. The interdependence, the interaction with evaporation/fission models, and the sensitivity of results to the choice of options in shown. The particular options used in the code comparisons benchmark calculations are compared with the other options possible
