1. Plot the differential cross section of the Rutherford scattering as a function of the scattering angle \Theta for three sensible choices of the lower limit of the angle. (use ZAu=79, ZHe=2, E=10keV).
2. Calculate the total cross section of the Rutherford scattering in unit of barns for your cut off angles.
Old naval ships fired 10kg cannon balls from a 250 kg cannon. It was very important to stop the recoil of the cannon, as otherwise the heavy cannon would go careening across the deck of the ship.
