As we study Rutherford gold foil scattering experiment we come to know about the structure of the atom,
But is the Gold foil experiment really was the idea of Rutherford❓
An article was published in Royal society 1909A, Volume 82, Page 495-500,
By H Geiger and E Mardsen in which they described the experiment performed by them in which they bombarded the alpha particle on a metal sheet and they observed that 1 out of 8000 are back scattered.
This was quite a surprise as alpha particle are heavy particle and that too moving with such a great velocity will ultimately result in much greater Momentum and such particle is back scattered by tiny particle at rest which was itself a surprise.
At the conclusion they said that bouncing back of alpha particle is a great surprise but no conclusion can be concieved out of it.
Later on in 1911 Rutherford performed the same experiment and reached to a conclusion that at a very small area a large group of mass is concentrated (Nucleus) which ultimately results in bouncing back of alpha particle.
