The targets had bulk density of 2.2 g/cm3 F1491 1 14 determined by weighing. F1491 1 15 INC-SOURCE Beam current was ~0.15 mu-A, total charge of ~0.3 mu-AhF1491 1 16 DETECTOR (HPGE) The measurements were performed using a gamma F1491 1 17 spectrometer with an ultrapure germanium detector F1491 1 18 ORTEC. The dead time during measurements did not F1491 1 19 exceed 5%.
