Internal conversion electron (ICE) spectra of thin (PU)-P-238,239,240 sources, measured with a windowless Peltier cooled silicon drift detector (SDD), were deconvoluted and relative ICE intensities were derived from the fitted peak areas. Corrections were made for energy dependence of the full-energy-peak counting efficiency, based on Monte Carlo simulations. A good agreement was found with the theoretically expected internal conversion coefficient (ICC) values calculated from the Brice database.
