Effects of electron scattering on Cherenkov light output

Scattering of electrons in a medium such as water must affect the coherence of Cherenkov radiation emitted by successive track segments. It is shown that coherence between short segments is not significantly affected by scattering and that the light output from long segments is not significantly dependent on coherence between them. Scattering of electrons in water has negligible effect on the energy radiated as Cherenkov light.
