Lattice Spacing Measurements and Avogadro’s Number
The present unsatisfactory situation concerning the value of Avogadro’s number has been briefly discussed by the authors in an earlier paper (1) in which was described a proposed method of direct measurement based on a new technique of X-ray interferometry (2,3) which provides a means for absolute determination of the lattice spacing of crystals.
