The targets had bulk density of 2.2 g/cm3 F149100100014 determined by weighing. F149100100015 INC-SOURCE Beam current was ~0.15 mu-A, total charge of ~0.3 mu-AhF149100100016 DETECTOR (HPGE) The measurements were performed using a gamma F149100100017 spectrometer with an ultrapure germanium detector F149100100018 ORTEC. The dead time during measurements did not F149100100019 exceed 5%.
