The angular distributions of the differential cross sections for the elastic scattering of 24-Mev deuterons were measured for the heavy elements, uranium, lead, gold, and tantalum. In general, the ratio of the differential cross section to the Rutherford cross section showed that the scattering is pure Rutherford scattering out to a critical angle. With increase in scattering angle- beyond the critical angle the decrease of the ratio was exponential with a small diffraction-like pattern superimposed. A classical model, developed by Nishida in an attempt to determine the value of the critical angle, was considered, and shown not to be in agreement with experiment. A semi-classical model was developed which does explain the shift of the critical angle with energy and atomic number for the reported experimental data, ranging in energy from 11 to 24 Mev. The time-dependent perturbation theory was used to calculate the probability of electric dipole disintegration of the deuteron in the Coulomb field of the target nucleus. Comparison with experimental data indicated that contrary to the conclusions reached by Nishida and Yntema, the electric dipole breakup of the deuteron may play the major role in the observed deviation from pure Rutherford scattering.
