While reproducing the Rutherford scattering experiment in an advanced laboratory class, a student uses a gold foil with thickness 28.8 nm. The radioactive source emits α particles at 7.70 MeV, and the detector is placed at 12.5 cm from the target foil. What fraction of the α particles is detected per unit area at an angle of 40.6°?
What fraction of the α particles will scatter to the angle given above or higher?
In a Rutherford scattering experiment, assume that an incident alpha particle (radius 1.80 fm) is headed directly toward a target gold nucleus (radius 6.23 fm).What energy must the alpha particle have to just barely “touch” the gold nucleus?
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 3.60 MeV alpha particle has a scattering angle of 180° and the gold nucleus does not recoil, determine the distance of closest approach of the alpha particle.
