Radioactivity : Rutherford's experiment

The result of their observations confirmed the existence of strong electric fields. Nevertheless an enigma remains: a few alpha particles were deflected. Rutherford asked a young assistant Ernest Marsden to see if alpha particles were subjected to a high deflection, and even bounced back, when they went through a thin gold foil. That was the case!
