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.
