Abstract
The Bothe-Geiger experiment has been repeated under improved conditions of time resolution, obtained by using stillbene scintillation counters. The recoil electron and scattered photon are emitted together within a time interval of less than 1.5× second. The electron and photon are also projected without a delay larger than 1.5× second after arrival of a quantum. The familiar concepts used in discussions of the Compton effect are shown to be valid.
