There are currently no models readily available that provide nucleon-nucleon (NN) spin dependent
scattering amplitudes at high energies (s ≥ 6 GeV2). This work aims to provide a model for calculating
these high energy scattering amplitudes. Such a model should prove useful for a variety of applications, including
our primary interest in describing final state interactions (FSI) in electromagnetic and electroweak nuclear
processes. I will discuss our approach to parametrize the NN system using Regge theory, which allows for a
relativistic description and full spin dependence. I will present the results of our fits to the NN system, as well
as their implementation to describe the FSI in the electrodisintegration of the deuteron.
