• G01N 23/005
• G01N 23/02 by transmitting the radiation through the material
• G01N 23/20 by using diffraction of the radiation by the materials, e.g. for investigating crystal structure; by using scattering of the radiation by the materials, e.g. for investigating non-crystalline materials; by using reflection of the radiation by the materials
• G01N 23/22 by measuring secondary emission from the material
