Three such pellets were 3167200100014 prepared. Monitor foils of Al (99.999% pure, 0.04 mm 3167200100015 thick) of the same diameter as the pellets were then 3167200100016 attached in the front and at the back of each sample. 3167200100017 DETECTOR (HPGE) a HPGe detector (ORTEC, model GEM - 60P, 3167200100018 crystal diameter: 70.1mm, crystal length: 72.3mm) 3167200100019 with a relative efficiency of 68% and an energy 3167200100020 resolution of 1.69 at 1332 keV for 60Co. The 3167200100021 efficiency of the detector was precalibrated using 3167200100022 various standard gamma sources. 3167200100023 METHOD (ACTIV) Irradiation lasted for 128 min with a yield 3167200100024 ~4 to 5 10**10 n/s. 3167200100025 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3167200100026 DECAY-MON (11-NA-24,14.959HR,DG,1368.633,1.) 3167200100027 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,,1990) 3167200100028 INC-SOURCE (D-T) Neutrons were produced by the T(d,n)4He 3167200100029 reaction with an effective deuteron beam energy of 3167200100030 134 keV and beam current of 230 mA. The tritium- 3167200100031 titanium (T-Ti) target used in the generator was 3167200100032 2.18 mg/cm2 thick. The neutron flux was monitored by 3167200100033 a uranium fission chamber so that corrections could be 3167200100034 made for small variations in the yield. 3167200100035 ERR-ANALYS (ERR-T) The main error sources in our work result 3167200100036 from: 3167200100037 (ERR-S,0.1,13.)
