  The goal of this research is to enable MCNP6 to produce high-energy light
fragments. These energetic light fragments may be emitted by our models through
three processes: Fermi breakup, preequilibrium, and coalescence. We explore the
emission of light fragments through each of these mechanisms and demonstrate an
improved agreement with experimental data achieved by extending precompound
models to include emission of fragments heavier than $^4$He.
