Web1-3: Rutherford’s Backscattering Experiment A key experiment in understanding the nature of atomic structure was completed by Ernest Rutherford in 1911. He set up an experiment that directed a beam of alpha particles (helium nuclei) through a gold foil and then onto a detector screen. According to the “plum-pudding” atomic model, electrons float around … WebRutherford understood what tremendous forces could be unleashed from the atom nucleus. In a famous 1934 experiment that opened the way to present-day fusion research (including ITER), he realized the fusion of deuterium (a heavy isotope of hydrogen) into helium, observing that "an enormous effect was produced." mineola water district ny
