Rutherford Scattering


The Simulation.

The Flash 5 movie simulates alpha particles being fired at a single gold nucleus one at a time to get a better feel for
what is happening. The alpha particle, nucleus and detector are naturally not to scale but the scattering is simulated with the correct formulae. 


  1. Enter a value for the energy of the alpha particle between 8 and 25MeV.
  2. Drag the alpha particle to a suitable start position with your mouse.
  3. Press the fire button.
  4. Press the next button to repeat.
