Rutherford performed a series of scattering experiments that challenged Thomson’s design. Rutherford noticed that when a beam of alpha particles (that happen to be now recognised to become helium nuclei) struck a thin gold foil, a number of the particles ended up deflected backward. These types of big deflections had been inconsistent Together with the plum-pudding design.
