An improved attempt of several national metrology institutes to replace the present definition of the kilogram with the mass of a certain number of 12 C atoms is described. This requires the determination of the Avogadro constant, N A , via the silicon route with a relative uncertainty better ...
For the first time an attempt has been made to determine the lattice parameter, density, and molar mass of an isotopically highly enriched silicon-28 crystal. The goal was to achieve an independent value of Avogadro's constant of accuracy equal or superior to current best values obtained from ...
