Elastic Scattering of 48-Mev Alpha Particles

Abstract
The angular distributions of alpha particles scattered elastically from Ag, Au, and Pb targets have been measured. Deviations by three to four orders of magnitude from pure Coulomb scattering have been observed beyond the forward angles. In addition, some regular structure appears in these distributions, but the main features can be described by an exponential falloff between 25° and 90°.
