Abstract
We have measured the rotational, velocity, and angular distributions of ammonia scattered from, single-crystal tungsten (100) and gold (111) surfaces. These are the first quantum-resolved measurements to be carried out for a polyatomic molecule scattered from a single-crystal surface. A quadruply differentially pumped molecular beam apparatus is used to produce an intense pulsed rotationally cold supersonic molecular beam of ammonia which is scattered from a well-characterized single-crystal surface.
