G001000100011 INC-SPECT the intensity ratio of the 17.6 and 14.7 gamma- G001000100012 rays bombarding the copper disk was 2.2 /1.0 G001000100013 METHOD (ACTIV) the copper disk was irradiated about 20 G001000100014 minutes (two times the half life of Cu-62) in order G001000100015 the number of Cu-62 nuclei in the disk to be G001000100016 saturated. G001000100017 DETECTOR (NAICR) a NaI(Tl) scintillator detector to monitor G001000100018 the gamma-radiation from the Li-7(p,g) reaction G001000100019 and to detect residual activity of Cu-62. G001000100020 the irradiated copper disk was attached to the G001000100021 front surface of the detector. G001000100022 ANALYSIS (DECAY) the saturated number of Cu-62 nuclei was G001000100023 determined from the number of 511 keV gamma-rays G001000100024 accumulated for 800 sec, 30 minutes after the irra- G001000100025 diation was turned off. from this number, the number G001000100026 of Cu-63 per unit area, the number of gamma-rays G001000100027 bombarding the disk per second, and the decay constant G001000100028 of Cu-62, the cross section was determined. G001000100029 CORRECTION corrections were made for self absorption of cu for G001000100030 the 511 keV gamma's G001000100031 STATUS (TABLE)data are taken from the text of G001000100032 J,KPS,17,(4),359,1984.
