Principle

The spectra of the X-rays that are reflected with various
different orientations by NaCl monocrystals are analysed. The
associated interplanar spacings are determined based on the Bragg
angles of the characteristic lines.

Tasks


Determine the intensity of the X-rays that are reflected by the
NaCl monocrystals with the orientations [100], [110] and [111] as a
function of the Bragg angle.

Assign the reflections to the corresponding lattice planes that
are given by way of their respective Miller indices.

Determine the lattice constant and calculate the interplanar
spacing.

Determine the mass of a cell and the number of atoms in the
cell.
