Precision measurements of the Planck and Avogadro constants
Horst Bettin, Kenichi Fujii, John Man +3
Precision measurements of the fundamental constants are tour de force of basic metrology, where the useful information is usually beyond the last digit of the measured value. They…

An accurate determination of the Avogadro constant by counting the atoms in a 28Si crystal
B. Andreas, Y. Azuma, G. Bartl +23
The Avogadro constant links the atomic and the macroscopic properties of matter. Since the molar Planck constant is well known via the measurement of the Rydberg constant, it is al…
