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 STATUS (TABLE) Table I+II of Phys.Rev.C99(2019)054617 S021900100055 HISTORY (20201012C) Wang Jimin (CNDC) S021900100056 (20201023R) The error correction for isomer ratios S021900100057 were obtained from Guangshun Li.
