Rutherford Scattering Apparatus, Different Diameter Targets, Touch Sensitive Tape, Large Protractor.

 

Code Number: 7D50.35

Demo Title: Rutherford Scattering

Condition: Excellent

Principle: Nuclear Scattering

Area of Study: Modern Physics

Equipment: 

Rutherford Scattering Apparatus, Different Diameter Targets, Touch Sensitive Tape, Large Protractor.

Procedure:

Place the scattering unit on a table and tape a new length of touch tape around the outer diameter.  Select and install the desired diameter target.  Place the cardboard screen over the target if it is desired to hide the target size from the class.  Find the center of the target by adjusting the screw bolt that governs the position of the gun.  Each Plexiglas shim is 1/2 cm wide.  By adding or subtracting these from the area between the adjusting bolt and the gun mounting shaft the gun may be easily moved in precise steps when shooting at the target.  Measuring the scattering angle of the shot pellet will give a reasonably accurate target diameter.
