Antiproton-Nucleus Interaction and Coulomb Effect at High Energies

The Coulomb effect in high energy antiproton-nucleus elastic and inelasticscattering from ¹²C and ¹⁶O is studied in the framework of Glauber multiplescattering theory for five kinetic energies ranged from 0.23 to 1.83 GeV. A microscopic shell-model nuclear wave functions, Woods-Saxon single-particle wave functions, and experimental pN amplitudes are used in the calculations. The results show thatthe Coulomb effect is of paramount importance for filling up the dips of differential cross sections. We claim that the present result for inelastic scattering of antiproton-¹²C is sufficiently reliable to be a guide for measurements in the verynear future. We also believe that antiproton nucleus elastic and inelastic scatteringmay produce new information on both the nuclear structure and the antinucleon-nucleon interaction, in particular the p-neutron interaction.
