Isotopic analysis of243Cm and244Cm by internal conversion electron spectrometry

Isotopic analysis of243Cm and244Cm has been tried by using a newly developed internal conversion electron spectrometer with high energy resolution. As a result, it was demonstrated that the above isotopes can be determined individually, accurately and precisely, and that the isotopic ratio is also possible to determined sensitively by measuring only the ratio of gross counting rate of internal conversion electrons to that of alpha-rays.
