Philip Harris Alpha Scattering Apparatus (Analogue)

This Alpha Scattering Apparatus is for demonstrating Rutherford scattering by means of a gravitational analogue of inverse square law repulsion.

The apparatus comprises a spun aluminium hill, a 12.5mm steel ball and a wooden launching ramp. The shape has been determined by varying its height above the base line by an amount based upon the reciprocal of the radius.

The launching ramp has a guide groove down its curved front face and index marks at 40mm, 60mm, 80mm and 100mm above the base to give a variety of known launching heights.

• Aluminium Hill Dimensions: (D)280mm x (H)60mm
• Launching Ramp Dimensions: (L)300mm x (W)48mm x (H)105mm
