A cubic crystalline powder sample is irradiated with the
radiation from a X-ray tube with a copper anode. A Geiger-Mueller
counter tube is automatically swivelled to detect the radiation
that is constructively reflected from the various lattice planes of
the crystallites. The Bragg diagram is automatically recorded. A
graphical evaluation procedure is used to assign the reflexes to
the individual lattice planes and to determine the corresponding
Bravais lattice type as well as the lattice constant of the
- Record the intensity of the Cu X-rays back scattered by a
cu-bic powder sample as a function of the back scattering
- Assign the Bragg reflexes to the respective lattice planes.
Determine which Bravais lattice type it has.
- Calculate the number of atoms in the unit cell.
