Rutherford Scattering and the Nucleus

Rutherford Scattering and the Nucleus Designed to confirm the "Plum Pudding" atomic model, the Geiger-Marsden experiments instead produced a shocking anomaly that shattered the prevailing theory. A tiny fraction of alpha particles fired at gold foil were deflected at extreme angles, some even rebounding—a result impossible for the Plum Pudding model's diffuse positive charge to generate. This led Rutherford to a revolutionary conclusion: the atom's positive charge and mass must be concentrated in a minuscule, dense nucleus capable of producing immense electrostatic repulsion. Rutherford's new atomic model and its scattering formula were subsequently verified with remarkable agreement by Geiger and Marsden themselves in more accurate follow-up experiments.
