M077600100014 SAMPLE The 197Au targets used were thin discs with a typical M077600100015 mass of about 200 mg, a thickness of 0.02 mm, and a M077600100016 diameter of 20 mm. M077600100017 DETECTOR (HPGE) HPGe detectors with relative efficienccies of M077600100018 90 or 60 %. M077600100019 METHOD (ACTIV) The 197Au(g,n) reaction produces the unstable M077600100020 nucleus 196Au that decays either to 196Pt by M077600100021 electron capture or positron emission (EC + beta+) M077600100022 or to 196Hg by beta decay (beta-).

M077600200004 ANALYSIS For the reaction 197Au(g,n)196Au activation yield M077600200005 (formulae (4) of the article) M077600200006 Y-act = N-act(196Au)/N-target(197Au) M077600200007 was measured where N-act is N-target multiplied M077600200008 reaction integrated cross section (formulae (1)) M077600200009 and therefore Y-act is determined as the reaction M077600200010 integrated cross section in units B*MEV normalized M077600200011 to N-target. M077600200012 ERR-ANALYS (DATA-ERR) The uncertainties presented in Fig. 8 are M077600200013 mainly from the determination of photon fluence. The M077600200014 statistical uncertainties are very small and in the M077600200015 order of about 0.5 - 2.0 %. M077600200016 (ERR-1) The systematic uncertainties arise from the M077600200017 extrapolation of measured photopeak efficiencies to M077600200018 the higher energies in 11B transitions (5 %). M077600200019 (ERR-2) The systematic uncertainties arise from the M077600200020 systematic deviation of measured photon fluence from M077600200021 the simulated curve (6 %). M077600200022 The total systematic errors have been obtained M077600200023 quadratically and amount to be about 7.8 %.
