The Moliere theory of multiple Coulomb scattering is modified to take into account the difference between the electric field of the nucleus and that of a point charge. A new expression is obtained for the angular distribution function assuming Gaussian distributions for the charge densities of the nucleus, protons, and the other structured particles. The effect of the finite size of the nucleus is shown to be important in the multiple scattering of particles with momenta greater than a few hundred MeV/c for a layer of matter of thickness greater than about a tenth of the radiation length. Approximate expressions are found for the distribution functions which are convenient for application to calculation of the passage of charged particles through matter.
