We compare R(E) for nucleus-nucleus systems (obtained from existing direct measurements and derived from elastic scattering data) with nucleon-nucleon and nucleon-nucleus data. The energy dependence of R(E) for nucleus-nucleus systems is found to be quite rapid; there appears to be no evidence for an energy independent, geometric R. Simple parameter free microscopic calculations are able to quantitatively reproduce the data and thus, emphasize the dominance of nucleon-nucleon interactions in medium energy nucleus-nucleus collisions. NUCLEAR REACTIONS Total reaction cross section theory, comparison to data for d, He3, ±+C12, Ca40, Zr90, Pb208 and C12+C12. Predictions for Ca40+Ca40, Ca40+Pb208, Pb208+Pb208. Energy range 3<Ein<1000 MeV.
