When polycrystalline samples are irradiated with X-rays a
characteristic diffraction pattern results. These Debye-Scherrer
reflections are photographed and then evaluated.
- Debye-Scherrer photographs are to be taken of powdered samples
of sodium chloride and caesium chloride.
- The Debye-Scherrer rings are to be evaluated and assigned to
the corresponding lattice planes.
- The lattice constants of the sample materials are to be
- The number of atoms in the unit cells of each sample are to be
