The decay of the excited Cs-133 can proceed by many paths, but the two most prominent photons emitted are E = 356 keV and E = 81 keV. Notably, gammas at E = 276, 302, and 382 keV will be detectable around (and may overlap with) the 356 keV peak. The sample gamma spectra obtained with the HPGe detector system are presented in Fig. 1. The spectra were initially visually scrutinized and analyzed with GammaVision-32 for the presence of impurity peaks. A specific search was carried out for pile-up and/or sum peaks arising from nearly-coincident emissions (X + X, γ … 더 보기 The conversion electron spectra acquired by the Mini-Orange based electron spectrometer are shown in Fig. 2a–d.
