Application of internal conversion electron spectrometry to analysis of A²⁴³Cm/²⁴⁴Cm mixture

Alpha-ray spectrometry is at present a powerful analytical tool for the identification and assay of the transuranium elements. However, the energy resolution is not necessarily excellent and a tailing toward the lower energy side in the spectrum is observed. Then, the possibility utilizing internal conversion electron spectrometry as the improved analytical tool was examined. In this paper the construction of an internal conversion electron spectrometer with excellent energy resolution using a silicon surface barrier detector and its application to analysis of a mixture of²⁴³Cm/²⁴⁴Cm is described.
