A vacuum double-crystal spectrometer for reference-free highly charged ions X-ray spectroscopy
P. Amaro, C. I. Szabo, S. Schlesser +10
We have built a vacuum double crystal spectrometer, which coupled to an electron-cyclotron resonance ion source, allows to measure low-energy x-ray transitions in highly-charged io…

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…
