TheLX-Ray Spectra from Radioactive Decay of Transuranium Elements

A bent crystal x-ray spectrometer is described, and some results are given on the analysis of L-series x-rays produced in radioactive decay processes of transuranium elements. There is generally good agreement between measured energy values of L-series lines and those predicted by the Moseley relationship. The relative intensities of the various lines produced in this case from γ-ray internal conversion, are compared with those emitted from uranium excited by electron bombardment and values reported of internal conversion excited x-rays in the region of lead.
