Abstract
The comparison of gamma ray energies to mass variation in a nuclear reaction provides a mean to close the metrological triangle connecting together the Planck and the Avogadro constant by measuring the molar Planck constant. We suggest a scheme to experimentally validate the angle interferometers used in this experiment. Further, the results of this validation can be used to transform the gamma spectrometer in a universal lattice constant comparator.
