||The scattering of X-rays by electrons was discovered by A. H. Compton in 1923. From careful measurements of the spectrum of scattered X-rays he showed that they suffered a shift to longer wavelengths. The size of the shift depended on the angle of scatter, and could be calculated by considering the process as a collision between a single photon and a single electron in which energy and momentum were conserved. The effect provides a striking demonstration of an electromagnetic wave behaving like a beam of "particles". The main purpose of this experiment is to observe the effect of gamma rays being scattered by material, and to measure their energy shifts as a function of their scattering angles.
