30Si Mole Fraction of a Silicon Material Highly Enriched in 28Si Determined by Instrumental Neutron Activation Analysis
Giancarlo D'Agostino, Marco Di Luzio, Giovanni Mana +3
The latest determination of the Avogadro constant, carried out by counting the atoms in a pure silicon crystal highly enriched in 28Si, reached the target 2x10-8 relative uncertain…

The correlation of the measurements by counting Si atoms
Michael Borys, Ingo Busch, Kenichi Fujii +9
An additional value of the Avogadro constant was obtained by counting the atoms in isotopically enriched Si spheres. With respect to the previous determination, the spheres were et…
