Abstract

By bombarding a poly-crystalline copper target with 15KeV electrons at lOmA direct current emission, a continuous spectrum of copper radiation was produced and made incident upon a mono-crystal of copper having a purity of 0.9999 and produced for the (111) planes. The mono-crystal of copper was aligned to produce Bragg reflection of the copper Ka lines, which occur in the moderate x-ray region, while simultaneously producing Pseudo-Kossel Ka lines in the same direction as that of the Bragg reflected lines. The spectral output was analyzed using a two quartz crystal spectrometer and multi-channel analyzer. The data shows an unusual increase in the copper Kai to Ka2 ratio, while exhibiting line width narrowing in both of the Ka lines, indicative of stimulated emission.
