A Universal Geometry for Calculable Frequency-Response Coefficient of LCR Standards and New 10-MHz Resistance and 1.6-MHz Quadrature-Bridge Systems
We present the results of a joint project to identify the origin of a discrepancy between the value of the Si lattice-parameter obtained by the Istituto Nazionale di Ricerca Metrologica and that obtained by the National Metrology Institute of Japan.

Summary: | We present the results of a joint project to identify the origin of a discrepancy between the value of the Si lattice-parameter obtained by the Istituto Nazionale di Ricerca Metrologica and that obtained by the National Metrology Institute of Japan. The re-evaluation of diffraction in the laser interferometry indicates that misalignment of the interfering beams could account for the observed difference |
