Etude de la structure de monocristaux de NaCl de différentes orientations

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

  1. Determine the intensity of the X-rays that ...
