A beam of neutral potassium atoms is directed to the surface of an MgO crystal, incident at an adjustable angle of from 20 to 80 degrees. Perpendicular to this beam is a slit system which defines a second beam of atoms which have been scattered by the crystal. This second beam is directed to the region between a pair of Stern-Gerlach magnet pole pieces. The intensity of the beam is measured by means of a Langmuir-Taylor surface ionization detector.
