Description gum 2006-02-17 18:03:06 CET 
According to the Application Developers Guide, when you define an optical
surface with the unified model but don't specify the refletion coefficients, the
default is Lambertian reflection. However, in this case GEANT defaults to Spike
reflection. See also the HyperNews:
