D440600100015 DETECTOR (LEGE) or LEPS low-energy photon spectrometer D440600100016 METHOD (ACTIV,EXTB,EDEG,GSPEC) Targets were irradiated one by D440600100017 one at different particle energy for 20 - 34 h with D440600100018 1 - 2.5 uA beam intensity in a Faraday-cup like D440600100019 target holder with -300 V suppression voltage. D440600100020 Absolute detector efficiency was determined at 10 cm D440600100021 wich then was converted to closer geometry 3 cm by D440600100022 measuring the same source at both distances several D440600100023 times. D440600100024 Spectra were recorded in every hour, than spectra were D440600100025 summ up to reduce the statistical uncertainty below D440600100026 10%. This spectrum summing was done separately for D440600100027 each of the studied peaks. D440600100028 Decay data were taken from NUDAT online data library. D440600100029 ERR-ANALYS (EN-ERR)The effective energy in each case is taken at D440600100030 the middle of the target. The energy loss is D440600100031 calculated with SRIM. The energy uncertainty D440600100032 determined by the initial beam-energy uncertainty D440600100033 of 0.3%. The effect of the target thickness and D440600100034 energy loss on beam-energy uncertainty is 0.005-0.05% D440600100035 and thus neglected. D440600100036 (ERR-T)The uncertainty of the cross sections D440600100037 are estimated in the standard way as the square root D440600100038 of the quadratic summation of the independently D440600100039 contributing parameters.
