Alpha particles are projected toward a gold foil from a distance that is sufficiently large to consider the Coulomb force negligible. The gold nuclei have 118 neutrons and 79 protons. If a 3.35 MeV alpha particle has a scattering angle of 180\deg and the gold nucleus does not recoil, determine the distance of closest approach of the alpha particle.
