An X-rayed crystal of Al203 was heated to a fairly high temperature where it emitted a very strong R line radiation of very large intensity. This may result from radiation centers that have been caused by the X-ray radiation transferring their energy to the levels of the R line or a reconversion from a different valence state such as Cr2 into Cr3. A special lead-shielded box was designed for placing over the X-ray tube and the spectrometer in order to provide protection from the X-rays scattered over a large angle.
