Abstract
The relative cross section of pair creation from a silicon single crystal h as been measured with a bremsstrahlung beam from 350 MeV electrons. A clear enhancement was observed above 230 MeV as expected from the theory based o n the type-B coherent effect. (C) 2000 Elsevier Science B.V. All rights res erved.
