Chemical Analysis of Surfaces by Use of Large-Angle Scattering of Heavy Charged Particles.
The Rutherford scattering of carged particles from the heavier elements and nuclear scattering and (alpha,p) reactions from the light elements result in energy spectra that are characteristic of the nucleus being bombarded. A simple apparatus for analyzing surfaces based on these ideas can be made by using an alpha source such as Cm244, a solid state detector, and an electronic pulse height analyzer.
