The average beam S022400100015 current was about 13 enA. S022400100016 SAMPLE Five targets of 89Y, each with thickness of about 1 S022400100017 mg/cm2. S022400100018 METHOD (STTA,ACTIV,GSPEC) A stacked foil online activation S022400100019 followed by an offline gamma-ray spectroscopy method. S022400100020 After the 12 hours irradiation, the gamma activity of S022400100021 the targets was measured offline using five HPGe S022400100022 detector groups. S022400100023 (BCINT) A high-precision current integrator was S022400100024 employed to measure the beam flux deposited at the S022400100025 Faraday cup, placed after the target. In order to S022400100026 repel the secondary electrons, the Faraday cup was S022400100027 biased with a negative 400 V electrode on the S022400100028 collector. S022400100029 DETECTOR (SIBAR) Two silicon surface- barrier detectors were S022400100030 mounted at +-30 deg to the beam direction for S022400100031 monitoring the elastic scattering of the 9Be S022400100032 projectiles by an thin Au foil placed upstream from S022400100033 the target stack. S022400100034 (HPGE) Each HPGe detector group consisted of two HPGe S022400100035 detectors were positioned 180 deg to each other. The S022400100036 data acquisition system was set such that single S022400100037 gamma-ray and gamma-gamma coincidence measurements S022400100038 could be performed simultaneously. The Ge crystal S022400100039 part of each detector was surrounded by a Pb annular S022400100040 cylinder of 3 cm thickness to reduce background from S022400100041 natural radioactivity. The energy calibration and S022400100042 absolute efficiency of the detectors was determined S022400100043 using a set of activity calibrated radioactive S022400100044 sources (60Co, 133Ba, and 152Eu) placed with the same S022400100045 geometry as the targets. S022400100046 ERR-ANALYS (ERR-T) The errors were estimated by taking into S022400100047 account following errors S022400100048 (ERR-1) Target thickness, about 3.% S022400100049 (ERR-2) Beam intensity, about 3.% S022400100050 (ERR-3) Detector efficiency, about 3.% S022400100051 STATUS (TABLE) Table I+II of Phys.Rev.C101(2020)014606 S022400100052 HISTORY (20201015C) Wang Jimin (CNDC) S022400100053 ENDBIB 51 0 S022400100054 COMMON 3 3 S022400100055 ERR-1 ERR-2 ERR-3 S022400100056 PER-CENT PER-CENT PER-CENT S022400100057 3. 3. 3.
