  • Abstract
    An isotopically enriched silicon crystal is recently available for a new determination of the Avogadro constant. Density comparison measurement is presented for enriched 28Si crystals by the pressure-of-flotation (PF) method. Relative density difference for 28Si spheres Avo28-S5 and Avo28-S8 is evaluated to be (2.6±0.9)×10-8.
