The Geiger–Marsden experiment was an experiment, that was carried out by Ernest Rutherford and his assistants Hans Geiger and Ernest Marsden at the University of Manchester between 1908 and 1913. A beam of alpha particles was shot at a thin gold foil.[1]
The scientists made three observations:
- The majority of the alpha particles went through the gold foil essentially undeflected.
- Some alpha particles were deflected by significant amounts.
- Occasionally some alpha particles were reflected. This observation led to the result that the plum pudding model was replaced by the nuclear model of the atom.
