| Zusammenfassung | For a new determination of the Avogadro constant using a 5 kg isotopically enriched silicon-single crystal, a sphere is used to measure the density of the crystal. The characterisation of the oxide layer on the sphere in order to determine the oxide mass is one of the critical tasks in the project. |
