4.  data for several channels (elastic, inelastic…)  range of energies (low versus high)  more theory What is needed for a successful nuclear reaction program? (the theorist’s wish) Optical potentials are an essential input to calculations should we not be working toward a CH89_ri and BG_ri? - nucleon elastic scattering of rare isotopes at least (p,p) then theory for (n,n) (?) - heavy ion elastic scattering of rare isotopes Other things that can help: elastic elastic breakup inelastic breakup (p,d) reaction models need to incorporate the structure: should we be using standard radius and diffuseness? by probing different energies we get a glimpse into different parts of the structure we are interested by probing different energies we can test whether our simplified structure assumptions are correct need accurate description of the reaction better control over uncertainties in inputs improved understanding of reaction dynamics keeping contact with underlying many body structure should we be using Hartree Fock densities, radii, etc for unstable nuclei? (often unable to even predict the correct bound state…)
