1. a Deviations from Rutherford scattering are expected when the alpha particles reach large energies. Suggest an explanation for this observation.
(a) Deviations from Rutherford scattering are expected when the alpha particles reach large energies. Suggest an explanation for this observation.
(b) Some alpha particles are directed at a thin foil of gold ( Z=79 ) and some others at a thin foil of aluminium ( Z=13 ). Initially, all alpha particles have the same energy. This energy is gradually increased. Predict in which case deviations from Rutherford scattering will first be observed.
