0 1 Information about the radius of a nucleus can be deduced from the
closest approach of alpha particles and from electron diffraction.
0 1 .1 Alpha particles, each with a kinetic energy of 5.59 MeV, are fired at a thin
foil made
79 of gold 197 Au atoms.
Some of the alpha particles are scattered through an angle of 180°.
Estimate the radius of a 197 Au nucleus from this information.
