Comparison of exact solution with Eikonal approximation for elastic heavy ion scattering
National Aeronautics and Space Administration, Langley Research Center, 1995 - Science - 18 pages
A first-order optical potential is used to calculate the total and absorption cross sections for nucleus-nucleus scattering. The differential cross section is calculated by using a partial-wave expansion of the Lippmann-Schwinger equation in momentum space. The results are compared with solutions in the Eikonal approximation for the equivalent potential and with experimental data in the energy range from 25A to 1000A MeV.
