The Conservation of Energy and Momentum in Compton Scattering

An experiment similar to that of Bothe and Maier-Leibnitz and others has been carried out to verify that in Compton scattering of 2.62-Mev quanta the scattered quantum and recoil electron are emitted without delay and in the relative directions demanded by the conservation laws. Better angular resolution and statistics and fewer experimental uncertainties than in the previous experiments were obtained. The results are in agreement with simultaneity and the conservation of energy and momentum.
