Raman Lines in X-Ray Spectra


A VERY interesting and significant phenomenon has been described by Ray 1 and by Majumdar,2 in which it is shown that a quantum of the radiation energy, say of the wave-length comprising the copper Kα lines, may, on passing through carbon or aluminium, be diminished by an amount sufficient for the ejection of a K electron from a carbon or an aluminium atom, and then pass on in the same or very nearly the same direction with a reduced energy hv′, and consequently a greater wave-length.
