A gold foil of thickness 2.0 m is used in a Rutherford experiment to scatter particles
Question:
A gold foil of thickness 2.0 μm is used in a Rutherford experiment to scatter α particles with energy 7.0 MeV.
(a) What fraction of the particles will be scattered at angles greater than 90º?
(b) What fraction will be scattered at angles between 45º and 75º?
(c) Use NA, ρ, and M for gold to compute the approximate radius of a gold atom. (For gold, ρ = 19.3 gm/cm3 and M = 197 gm/mol.)
