A0717001 20 (ACTIV) Three different irradiation-detection periods A0717001 21 were employed: first, the cycle was a 120-S A0717001 22 irradiation followed a 420-S g-ray detection, and a A0717001 23 total of 143 samples were measured; A0717001 24 second, 10-min irradiation followed by 60-min detectionA0717001 25 and three samples; A0717001 26 third, 100-min irradiation followed by 48-H detection A0717001 27 for one sample. A0717001 28 (GSPEC) A0717001 29 ANALYSIS (DECAY) A0717001 30 SAMPLE A molten natural lead target with a thickness of about A0717001 31 5.2 g/cm2 (thick enough to stop the 600-MeV 18O A0717001 32 incident beam). The temperature of the molten lead A0717001 33 target material was continuously kept at about 700.C A0717001 34 during the 18-O beam irradiation. A0717001 35 DETECTOR (HPGE) A0717001 36 (BGO) A large bismuth germanate detector (14x7x5 cm3) A0717001 37 and a beta-ray detector (unknown type) A0717001 38 ERR-ANALYS (DATA-ERR) Measurement errors of the experimental crossA0717001 39 sections are estimated to be 15% to 30%, including the A0717001 40 systematic error from collection efficiency A0717001 41 determination, statistical error of gamma-ray counts, A0717001 42 and count contamination to the characteristic gamma- A0717001 43 ray used in cross-section calculation from neighboring A0717001 44 gamma rays. A probable additional error would come A0717001 45 from the uncertainty of the data for gamma-ray A0717001 46 branching ratio. A0717001 47 A probable example is the unusual lower measurement A0717001 48 cross section for 193-Hg, which has not been clarified A0717001 49 clear so far. A0717001 50 COMMENT -By authors. To evaluate independent cross sections A0717001 51 for Hg isotopes, special care has been exercised over A0717001 52 the following difficulties: A0717001 53 1. Half-lives of some Hg isotopes are very short in A0717001 54 comparison with the time elapsed before starting the A0717001 55 measurement (typically 20 sec after irradiation); A0717001 56 2. For some Hg isotopes gamma-decay schemes and/or A0717001 57 absolute gamma-ray branching ratios have not been A0717001 58 measured; A0717001 59 3. Gamma rays which should be characteristic of some A0717001 60 Hg isotopes including relevant daughter or A0717001 61 granddaughter nuclides are too weak to be identified A0717001 62 or overlapping with other gamma rays.
