  • Abstract
    The first investigations of lattice parameter, density and molar mass of an enriched silicon 28 single crystal are reported. The unexpectedly large amount of impurity atoms in the material at present limits the goal of improving the uncertainty in a new determination of the Avogadro constant.<>
