The 3293200100014 experimental tritium titanium target possesses a 3293200100015 thickness of 2.65 mg/cm2. The neutron yield is 3293200100016 (4 - 5) E10 n/s. 3293200100017 METHOD (ACTIV) The samples were irradiated continuously for 3293200100018 2 h. After irradiation, the sample cooling time were 3293200100019 7.6 days for 132Xe and 6.3 - 17.9 h for 134Xe. 3293200100020 DETECTOR (SIBAR) To compensate for variations in neutron flux, 3293200100021 alpha-particles are detected by an Au-Si surface 3293200100022 barrier detector at 135 deg in the direction of the 3293200100023 incoming deuteron beam. 3293200100024 (HPGE) A high-purity germanium (HPGe) detector is 3293200100025 used to quantify the gamma counts of the resultant 3293200100026 nuclei. 3293200100027 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3293200100028 DECAY-MON
