Three-dimensional model of a split-crystal x-ray and neutron interferometer
Carlo Paolo Sasso, Giovanni Mana, Enrico Massa
The observation of neutron interference by using a crystal interferometer having a separate analyser opens the way to the construction and operation of interferometers with vast ar…
Neutron interference from a split-crystal interferometer
Hartmut Lemmel, Michael Jentschel, Hartmut Abele +5
We report the first successful operation of a neutron interferometer having a separate beam recombining crystal. We achieved this result at the neutron interferometry setup S18 at…
Measurement of the miscut angle in the determination of the Si lattice parameter
Carlo P. Sasso, Giovanni Mana, Enrico Massa
The measurement of the angle between the interferometer front mirror and the diffracting planes is a critical aspect of the Si lattice-parameter measurement by combined x-ray and o…
Wavefront errors in a two-beam interferometer
G Mana, E Massa, C P Sasso
The paper deals with the impact of wavefront errors, due to the optical aberrations of a two-beam interferometer, on the period of the travelling fringe observed by integrating the…
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…
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…
