Total reaction cross section forC12onC12,Ca40,Zr90, andPb208between 10 and 35 MeV/nucleon

Elastic scattering angular distributions for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ on ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$, ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$, and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ were measured for projectile energies between 10 and 35 MeV/nucleon. Total reaction cross sections were extracted by an optical model analysis and compared to the prediction of the Glauber model. This comparison suggests that the nucleus-nucleus total reaction cross section at intermediate and high energies is governed by the nucleon-nucleon cross section.
