Indirect Measurement Predictions Ch. 1, Act. 6
Earnest Rutherford (1911)“The Gold Foil Experiment” • Bombarded gold foil with particles from the radioactive decay of uranium238. • Most of the particles traveled through very thin gold foil without being deflected. • Occasionally, particles would deflect, sometimes at angles > 90o. • Results show that the dense positive charge is centrally located in the nucleus.
