Nucleon Scattering from Very Light Nuclei: Intermediate Energy   Expansions for Transition Potentials and Breakup Processes
  Optical potentials for elastic p-d scattering and the coupled processes p+$^3$He $\rightarrow$ p+$^3$He and p+$^3$He $\rightarrow$ d+d are derived in the Faddeev-Yakubovsky framework with special emphasis on leading order terms, which are expected to be valid at intermediate energies. In addition, equations for the fragmentations $^3$He(p,ppp)n and $^3$He(p,pp)d are derived within the same framework. Again leading order terms for intermediate energies are considered.
