Answer all questions in this section.
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 of
(
gold 197 )
79 Au atoms.
Some of the alpha particles are scattered through an angle of 180°.
Estimate the radius of a 197
79 Au nucleus from this information.
[3 marks]
radius of nucleus = m
0 1 . 2 Explain why your answer to Question 01.1 is an estimate.
