Abstract：
The differential cross sections of the antiproton elastic scattering on the ¹²C, ^16,18O, ⁴⁰Ca and ²⁰⁸Pb at the energies of 50 MeV and 180 MeV are calculated and analyzed by the optical potential model. It shows that the antiproton optical potential has a strong absorption property. In making optical potential best fit to the experimental data, it is found that the diffuseness parameters can vary only in a narrow region and increase with heavier nuclei. The real part of the optical potential is very shallow. The absorption coefficients approach to zero inside the target nucleus. Thus, the elastic scattering takes place at the surface region of a nucleus.
