<P> The Geiger -- Marsden experiment ( s ) ( also called the Rutherford gold foil experiment ) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where all of its positive charge and most of its mass are concentrated . They deduced this by measuring how an alpha particle beam is scattered when it strikes a thin metal foil . The experiments were performed between 1908 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester . </P>
