The new definition of the kilogram was implemented on May 20, 2019. The kilogram is presently defined by the Planck constant. On the basis of the new definition, the kilogram will be realized at the National Metrology Institute of Japan by the X-ray

To realize the kilogram using the X-ray crystal density method, 28Si crystals grown by the floating zone method were employed. Samples cut from two 28Si crystals, the AVO28 crystal (Si28-10Pr11 crystal) and the Si28-23Pr11 crystal, were analyzed by m

For the future realization of the kilogram using the X-ray crystal density (XRCD) method, isotopically enriched silicon crystals grown by the floating zone method are employed. In this paper, we present quantitative electron paramagnetic resonance (E

To realize the kilogram with high accuracy using the x-ray crystal density method, mass deficit correction to account for the number of vacancy defects in silicon-28 crystals is necessary. In this paper, we present the results of electron paramagneti

To determine the Avogadro constant N A by the x-ray crystal density method, the density of a 28Si-enriched crystal was determined by absolute measurements of the mass and volume of a 1 kg sphere manufactured from the crystal. The mass and volume were
