The thickness of the solid 3281400100015 tritium-titanium (T-Ti) target applied to the 3281400100016 generator was 2.19 mg/cm2. 3281400100017 SAMPLE Natural zirconium foils (purity: 99.99%, thickness: 3281400100018 3.04-3.09 mm) were formed into round disks with a 3281400100019 diameter of 20 mm. Four such round disks were 3281400100020 prepared. Niobium monitor foils (purity: 99.95%, 3281400100021 thickness: 0.62 mm) of the same diameter as the 3281400100022 zirconium sample were subsequently fixed at the front 3281400100023 and back of each zirconium sample, which was wrapped 3281400100024 in a cadmium foil (purity: 99.95%, thickness: 1 mm) 3281400100025 METHOD (ACTIV) The samples were irradiated for 6.2-7.5 h. 3281400100026 The samples were placed at 0 to 135 deg angles 3281400100027 relative to the direction of the deuteron beam, and 3281400100028 the distances from the center of the T-Ti target were 3281400100029 approximately 40-50 mm. 3281400100030 DETECTOR (SIBAR) An Au-Si surface barrier detector was used at 3281400100031 135 deg accompanying alpha particle tube to correct 3281400100032 small variations in neutron flux. 3281400100033 (HPGE) GEM-60P coaxial high-purity germanium ORTEC 3281400100034 detector made in the USA (crystal diameter: 70.1 mm, 3281400100035 crystal length: 72.3 mm) with a relative efficiency 3281400100036 of 68% and an energy resolution of 1.69 keV at 1.332 3281400100037 MeV. 3281400100038 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3281400100039 DECAY-MON (41-NB-92-M,10.15D,DG,934.44,0.9915)
