G410400100013 DETECTOR (HPGE) A semiconductor HPGe detector (Canberra GC-2018)G410400100014 was used with resolutions of 0.8 keV and 1.8 keV (FWHM)G410400100015 for the energies Eg = 122 keV and 1332 keV. The G410400100016 absolute registration efficiency of the detector was G410400100017 calibrated with a standard set of gamma-ray sources G410400100018 22Na, 60Co, 133Ba, 137Cs, 152Eu and 241Am. G410400100019 SAMPLE The targets were made of natural molybdenum, which G410400100020 were thin discs with a diameter of 8 mm and a thicknessG410400100021 of 0.11 mm, which corresponded to a mass of 57-60 mg.
