Absolute X-ray energy measurement using a high-accuracy angle encoder
Takahiko Masuda, Tsukasa Watanabe, Kjeld Beeks +16
This paper presents an absolute X-ray photon energy measurement method that uses a Bond diffractometer. The proposed system enables the prompt and rapid in-situ measurement of phot…
X-ray pumping of the Th-229 nuclear clock isomer
Takahiko Masuda, Akihiro Yoshimi, Akira Fujieda +27
Thorium-229 is a unique case in nuclear physics: it presents a metastable first excited state Th-229m, just a few electronvolts above the nuclear ground state. This so-called isome…
Improved measurement results for the Avogadro constant using a 28Si-enriched crystal
Y Azuma, P Barat, G Bartl +26
New results are reported from an ongoing international research effort to accurately determine the Avogadro constant by counting the atoms in an isotopically enriched silicon cryst…
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…
