Rutherford Scattering II

Rutherford Experiment: Extended version for 4th year.

Here are some definitions that may prove to be useful:

The number of scattering centres in the target is related to the thickness of the foil and the density of the material via N0 = (a x d) x  x A0/ A , where

• A0 = Avogadro’s number = 6.0222 x 10²³ atoms /mole.
• A = atomic weight of the target in gm/mole.
•  = density of the material (19.3 gm/cm³ for Au, 2.7 gm/cm³ for Al).
• d = thickness of the target (2 micrometers = 2 microns for Au, 7 microns for Al).
• a = area of the target intercepted by the beam.
