Alpha particles scattering analogue (plastic hill and ramp)

Alpha particles scattering analogue (plastic hill and ramp)

The plastic hill and ramp can be used as an analogue for alpha particles (ball bearings) being scattered by the electric field around a nucleus. The hill is a 1/r shape - the same as the electrical potential around a nucleus due to its electric charge. This piece of apparatus is available from Philip Harris.
