Present Status of the Avogrado Constant Determination from Silicon Crystals with Natural Isotopic Composition
The determination of the Avogadro Constant from selected silicon crystals is described. The density molar mass and lattice spacing of the 2 crystals were measured at NMIJ, PTB, IRMM, IMGC and NIST.
When all date are combined, it leads to the Avogadro Constant of 6.022 135 3 (21) 10^23 mol^-1.
