Spectroscopic Evidence of J-Transformation of X-rays

Abstract

The relation between the atomic number of a radiator and the wave-lengths of its X-ray emission spectrum of K-series is generally assumed to be the regular one described by Sommerfeld's extension of Bohr's idea to X-ray spectra. Well-marked irregularities, however, have not received attention in the literature of the subject; it is the object of this note to direct attention to them.
