In the 3293600100012 case of deuterium beams, the average energy value was 3293600100013 135 keV, and the average intensity value was 240 uA. 3293600100014 The thickness of the tritium-titanium was 2.65 mg/cm2.3293600100015 METHOD (ACTIV) The radiation lasted for two to three hours. 3293600100016 For this experiment, two measurements were taken 3293600100017 from each sample. The second data-set was taken 4.7 d 3293600100018 later, nearly 12 times the half-life of the ground 3293600100019 state of 127gTe, and the first set was taken between 3293600100020 0.5 and 27 h after irradiation. t1 was cooling time, 3293600100021 t2 was measuring time. 3293600100022 +-----------------------------------------------------+3293600100023 Sample Irradiation First Second 3293600100024 no.

For 60Co, the 3293600100034 detector's efficiency was 68%, and its energy 3293600100035 resolution was 1.69 keV at 1.332 MeV. 3293600100036 SAMPLE (52-TE-128,NAT=0.3174) Tellurium samples with a 3293600100037 natural isotopic composition weigh between 3.4 and 3293600100038 4.1 g and are 99.99% refined. The sample was a disc 3293600100039 with a diameter of 20 mm. Five samples and 10 3293600100040 monitors made of 99.99% pure niobium foil and 99% 3293600100041 pure zirconium with the same diameter were 3293600100042 fabricated. 3293600100043
