Themethod consists in receiving the beam of scattered X-rays into anX-ray spectroscope, whereby it is deflected against an ionization-chamber or a photographic plate at a particular point, of which the Jib SYSTEM location is the measure of the wave-length. An image can be madeon the same plate at the point where the beam would have struck it,if it had retained the frequency of the primary beam. The twoimages then stand sharpK- and widely apart. Indeed it is not neces-sary to make a special image to mark the place on the plate wherea scattered beam of unmodified wave-length would fall, for there.

See footnote 13 nearly always is such a beam aiui such an image. .\ plausible ex-planation is easy to find; one has onh to assume that the ciuaniacomposing this beam have rebounded from electrons so rigidK boundinto atoms that they did not budge when the impinging quanta strucktiuiu. ,uid liusi were reflected as fnnii an inimoxabli wall. The iliagrani in Iig. 6 is designed to illustrate the relations between the energyof the primary quantum (radius of the dotted semicircle), the encrg> of the re-bounding (juantum (radius of the upper continuous curve), and the energy of therecoiling electron (radius of the lower continuous curve). Thus the two arrowsmarked with a .S are proportional respecti\el\ to the energies of the secondaryquantum and of the recoiling electron, when the encounter has taken place in sucha fashion that
