A0240 1 9 METHOD (BCINT,STTA,ACTIV,EXTB,EDEG). A0240 1 10 Thin targets were irradiated simultaneously at A0240 1 11 different energies by stacked-foil technique. Thick A0240 1 12 targets were irradiated one-at-a-time with a thin A0240 1 13 standard in the same stack, or with a thick standard A0240 1 14 from two successive irradiations. A0240 1 15 DETECTOR (GELI) Two Ge(Li) detectors, having active volumes of A0240 1 16 l6 cm3 and 30 cm3 A0240 1 17 ANALYSIS Absolute cross-sections were calculated A0240 1 18 based on the assumption that the reactions were A0240 1 19 attributed entirely to a single reaction on a A0240 1 20 specific target nuclide. A0240 1 21 Each of the cross-sections shown in 'data-section' A0240 1 22 represents an average value of 2-3 replicates. A0240 1 23 ERR-ANALYS (ERR-T) The estimated absolute uncertainty in the A0240 1 24 cross sections includes: A0240 1 25 * uncertainty in the determination of total A0240 1 26 beam current, A0240 1 27 * uncertainty in the half-lives of nuclides, A0240 1 28 * uncertainty in the determination of disintegration A0240 1 29 rates, A0240 1 30 * the uniformity of thickness of targets, A0240 1 31 * possibility of recoil gas losses during irradiation.A0240 1 32 (ERR-S) Average deviation.
