Abstract: | The Coulomb effect in high energy antiproton-nucleus elastic and inelastic
scattering from 12C and
16O is studied in the framework of Glauber multiple
scattering 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 that
the 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 very
near future. We also believe that antiproton nucleus elastic and inelastic scattering
may produce new information on both the nuclear structure and the antinucleon-nucleon interaction, in particular the
p-neutron interaction. |
