Chapter 39: Problem 28
An experiment similar to the Geiger-Marsden experiment is done by bombarding a \(1.00-\mu \mathrm{m}\) -thick gold foil with 8.00 - \(\mathrm{MeV}\) alpha particles. Calculate the fraction of particles scattered at an angle a) between \(5.00^{\circ}\) and \(6.00^{\circ}\) and b) between \(30.0^{\circ}\) and \(31.0^{\circ}\) (The atomic mass number of gold is \(197,\) and its density is \(\left.19.3 \mathrm{~g} / \mathrm{cm}^{3} .\right)\)
