In order to fully test his model of the atom, Rutherford assumed that the scattering of the alpha particles was due to the inverse-square electrostatic repulsion between the alpha particle and the positively-charged atomic nucleus. Based on this assumption, he calculated the proportions of alpha particles scattered at di ff erent angles, and compared these theoretical proportions to those measured experimentally. Rutherford’s alpha scattering experiments were the first experiments in which individual particles were systematically scattered and detected. This is now the standard operating procedure of particlewere systematically scattered and detected....
