What did Rutherford's tering experiment show?

In physics, Rutherford tering is a phenomenon that was explained by Ernest Rutherford in 1909, and led to the development of the Rutherford model (planetary model) of the atom, and eventually to the Bohr model. It is now exploited by the materials ytical technique Rutherford backtering. Rutherford tering is also sometimes referred to as Coulomb tering because it relies only upon static electric (Coulomb) forces, and the minimal distance between particles is set only by this potential.
