Abstract
An overview is given on the first observation of Doppler broadening due to electron momentum in the τ rays emitted from in-flight two-photon annihilation when highly energetic positrons traverse thin foils. This observation can serve as basis in the development of a new probe of electron momentum distributions similar to Compton or electron scattering technique.
