THE EFFECT OF MULTIPLE-SCATTERING AND DENSITY DISTRIBUTION ON THE ELASTIC-SCATTERING OF HIGH-ENERGY ELECTRONS

Electron-nucleus elastic scattering is calculated by means of the mult iple-scattering theory of Glauber and the eikonal approximation applie d to different forms of nuclear charge distribution. The differences b etween the calculated cross-sections are examined and compared with th e experimental data for C-12, O-16, Ca-40 and Pb-208 nuclei at differe nt energies. A very good agreement with the experimental data, at high er angles, is obtained for densities other than Gaussian. The multiple -scattering shows even better agreement than the eikonal approach for lighter nuclei, especially at the diffraction dip.
