Lanzhou (HIRFL) S021900100013
INC-SOURCE The collimated 9Be beam with an initial energy of S021900100014
50.3 MeV was delivered by HIRFL. The beam current was S021900100015
about 20 enA. S021900100016
SAMPLE Two stacks of 181Ta targets having thickness in the S021900100017
range of 0.43-0.59 mg/cm2 S021900100018
METHOD (STTA,ACTIV,GSPEC) A stacked foil online activation S021900100019
followed by an offline gamma-ray spectroscopy method. S021900100020
After the 13 hours irradiation for two stacks in two S021900100021
individual runs, the activated targets were S021900100022
transferred to a separate laboratory for offline S021900100023
measurements. The first activity measurement was done S021900100024
by the eight CANBERRA High Purity Germanium (HPGe) S021900100025
detector groups. The second activity measurement was S021900100026
carried out about 2 months after the activation, S021900100027
using a commercial ORTEC Compton Suppression Counting S021900100028
System. S021900100029
(BCINT) The beam flux was determined from the charge S021900100030
collected in the Faraday cup installed after the S021900100031
targets by using a precise current-integrator device. S021900100032
The Faraday cup was biased with negative 400-V S021900100033
electrodes. S021900100034
DETECTOR (SIBAR) Two Si (Au) surface-barrier detectors, at S021900100035
angles of +-30 deg with respect to the beam direction, S021900100036
were used to detect the elastically scattered 9Be S021900100037
particles form an Au foil placed upstream from the S021900100038
target stack. S021900100039
(HPGE) Each HPGe detector group consisted of two HPGe S021900100040
detectors in a face-to-face geometry, where single S021900100041
gamma-ray and gamma-gamma coincidence measurements S021900100042
could be performed simultaneously. The Ge crystal S021900100043
part of detector was surrounded by a Pb annular S021900100044
cylinder of 3 cm thickness to reduce background from S021900100045
natural radioactivity. The absolute efficiency of the S021900100046
detector was determined by using a set of calibrated S021900100047
radioactive sources (60Co, 133Ba, and 152Eu) placed S021900100048
in front of the HPGe detector. S021900100049
ERR-ANALYS (ERR-T) The systematic uncertainties are added in S021900100050
quadrature to the statistical errors to get the total S021900100051
errors S021900100052
(ERR-1) Target thickness, about 3.% S021900100053
(ERR-2) Detector efficiency, about 5.% S021900100054
