WebRamsauer-Townsend effect. The Ramsauer-Townsend effect is a physical phenomenon involving the scattering of low-energy electrons by atoms of a noble gas. Since its explanation requires the wave theory of quantum mechanics, it demonstrates the need for physical theories more sophisticated than those of Newtonian physics. WebThe Townsend theory of dielectric breakdown of gases does not apply at low gas density, where the mean free path of electrons maybe of the order of the dimensions of the discharge chamber.
