Geiger and Marsden (1909) observed backward-scattered (θ ≥90°) α particles when a beam of energetic α particles was directed at a piece of gold foil as thin as 6.0 x 10-7 m. Assuming an α particle scatters from an electron in the foil, what is the maximum scattering angle?
In a scattering experiment, you concentrate on Alpha particles with impact parameters b=0, 1×10^-3, and 1×10^0 mm. For which b will the behavior of the Alpha particle be very different in Thomson's and Rutherford's models and for which will it be nearly similar?
Problem 9: Rutherford Scattering
A gold foil (5.9×1022 atoms/cm³) of "hair" thickness 80 µm is used in a Rutherford experiment to scatter a
particles with energy 5 MeV. Find the fraction of particles scattered at angles 0 > 30°.
