P6.5.2.1 Rutherford scattering: Measuring Scattering Rate as Function of Scattering Angle and Atomic NumberRutherford scattering: Measuring Scattering Rate as Function of Scattering Angle and Atomic Number The experiment P6. 5. 2. 1 reproduces these observations using an Am 241 preparation in a vacuum chamber. The scattering rate N() is measured as a function of the scattering angle using a Geiger Mller counter tube. As scattering materials, a sheet of gold leaf (Z = 80) and aluminum foil (Z = 13) are provided. The scattering rate confirms the relationship
