El experimento consistió en mandar un haz de partículas alfa sobre una fina lámina de oro y observar cómo dicha lámina afectaba a la trayectoria de dichos rayos. Las partículas alfa se obtenían de la desintegración de una sustancia radiactiva, el polonio. Para obtener un fino haz se colocó el polonio en una caja de plomo, el plomo detiene todas las partículas, menos las que salen por un pequeño orificio practicado en la caja. Perpendicular a la trayectoria del haz se interponía la lámina de metal. Y, para la detección de trayectoria de las partículas, se empleó una pantalla con sulfuro de zinc que produce pequeños destellos cada vez que una partícula alfa choca con él. Según el modelo de Thomson, las partículas alfa atravesarían la lámina metálica sin desviarse demasiado de su trayectoria:
