Rutherford Gold Foil Experiment - The Atomic Model

They fired a beam of alpha particles at a thin metal foil. Just so you know, alpha particles (alpha rays) were already known by people of Rutherford's time because Rutherford himself identified them only a decade earlier from when he decided to hold the experiment.

Geiger-Marsden experiments - Wikipedia

The Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced this after measuring how an alpha particle beam is scattered when it strikes a thin metal foil.
