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 $\gamma$-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.
