Rutherford's Scattering Experiment (Theory) : Class 9 ...

Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil. He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about 1000 atoms thick. α-particles are doubly-charged helium ions.

About Rutherford's Gold Foil Experiment | Sciencing

Apr 25, 2017· The gold foil experiment consisted of a series of tests in which a positively charged helium particle was shot at a very thin layer of gold foil. The expected result was that the positive particles would be moved just a few degrees from their path as they passed through the sea of positive charge proposed in the plum pudding model. The result ...

For his experiment, he set the foil in front of the particle source. Behind the foil, he placed a fluorescent screen. The screen would show a spark of light whenever it was struck by an alpha particle. Thus, he could see whether any alpha particles were able to pass through the atoms in the gold foil. The actual results were amazing.
