The Scattering of 100-Mev Electrons from a Heavy Nucleus

This paper describes and gives the results of a calculation of the scattering of 100-Mev electrons from a heavy nucleus with atomic number $Z=82.2$. For 100-Mev electrons the reduced de Broglie wave-length is about one-fourth of the radius of a lead nucleus and appreciable deviations from pure Coulomb scattering are to be expected. Three different models of the nucleus are considered. In the primary case, the nucleus is assumed to have a uniform charge distribution within its radius. The scattering for this model is calculated by the exact phase-shift method. In the two other models the effects on the scattering of varying the radius and non-uniform charge distributions are investigated. The last two calculations are carried out by perturbation on the first.
