The average beam S022200100014 current was about 13 enA. S022200100015 SAMPLE Five targets of 89Y, each with 197Au backing of about S022200100016 1 mg/cm2. S022200100017 ANALYSIS The authors assumed the number of the products escaped S022200100018 from the upstream Au foil (30% of the products) is S022200100019 equal the number of the products escaped to the S022200100020 downstream Au foil. S022200100021 The radioactivity of the first foil is much lower than S022200100022 the other four foils due to this reason and its S022200100023 effective beam energy is not given in Table II. S022200100024 METHOD (STTA,ACTIV,GSPEC) A stacked foil online activation S022200100025 followed by an offline gamma-ray spectroscopy method. S022200100026 After the 12 hours irradiation, the activity of the S022200100027 targets was measured offline using five HPGe detector S022200100028 groups in a separate laboratory. S022200100029 (BCINT) The beam flux was calculated by the total S022200100030 charge collected in the Faraday cup placed behind the S022200100031 targets using a high precision current integrator. S022200100032 The Faraday cup was biased with a negative 400 V S022200100033 electrode on the collector to repel the secondary S022200100034 electrons. S022200100035 DETECTOR (SIBAR) During the bombardments, two silicon surface- S022200100036 barrier detectors were placed at +-30 deg to the beam S022200100037 for monitoring the elastic scattering of the beam S022200100038 particles by an Au foil placed upstream from the S022200100039 target stack. S022200100040 (HPGE) Each HPGe detector group consisted of two HPGe S022200100041 detectors positioned 180 deg to each other, where S022200100042 single gamma-ray and gamma-gamma coincidence S022200100043 measurements could be performed simultaneously. The S022200100044 Ge crystal part of each detector was surrounded by a S022200100045 Pb annular cylinder of 3 cm thickness to reduce S022200100046 background from natural radioactivity. In addition, S022200100047 Pb blocks of 6 cm thickness were inserted between S022200100048 each adjacent detector group to shield gamma-rays S022200100049 from neighboring targets. The absolute efficiency of S022200100050 the detectors was determined using a set of activity S022200100051 calibrated radioactive sources (60Co, 133Ba, and S022200100052 152Eu) mounted with the same geometry as the targets.
