Geiger Marsden experiment
The Rutherford experiment (also known as the Gold foil experiment or the Geiger-Marsden experiment) was an experiment to probe the structure of the atom performed through Hans Geiger and Ernest Marsden in the year of 1909, under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester. The unexpected results of the experiment established for the first time the existence of the atomic nucleus and leading to the downfall of the plum pudding model of the atom, and the growth of the Rutherford (or planetary) model.
