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…
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…
Improved frequency measurement of the - clock transition in Sr using the Cs fountain clock at NMIJ as a transfer oscillator
Takehiko Tanabe, Daisuke Akamatsu, Takumi Kobayashi +10
We performed an absolute frequency measurement of the - transition in Sr with a fractional uncertainty of , which is less than one thi…
Ultra-broadband dual-comb spectroscopy across 1.0-1.9 μm
Sho Okubo, Kana Iwakuni, Hajime Inaba +4
We have carried out dual-comb spectroscopy and observed in a simultaneous acquisition a 140-THz-wide spectrum from 1.0 to 1.9 μm using two fiber-based frequency combs phase-locked…
