Principle

Laue diagrams are produced when monocrystals are irradiated with
polychromatic X-rays. This method is primarily used for the
determination of crystal symmetries and the orientation of
crystals. When a LiF monocrystal is irradiated with polychromatic
X-rays, a characteristic diffraction pattern results. This pattern
is photographed and then evaluated.

Tasks


The Laue diffraction of an LiF mono-crystal is to be recorded
on a film.

The Miller indices of the corresponding crystal surfaces are to
be assigned to the Laue reflections.
