Measurement time 24-36hr4011700100015 DETECTOR (GELI) Germanium-lithium detector with sensible 4011700100016 volume 10 cm**3 was situated on distance 15cm from 4011700100017 sample. 4011700100018 Resolution of detector was 3.5keV at 1 MeV and 4011700100019 8 keV at 7 MeV. 4011700100020 ANALYSIS Gamma intensities were obtained using the relation: 4011700100021 sum(Igamma*Ei)=Bn, were Ei - i-th gamma energy, 4011700100022 Bn - neutron binding energy. 4011700100023 It's valid, if all lines were taken into account - 4011700100024 values of Igamma are somewhat overestimated, not more 4011700100025 than 12% (checked intensity balance through each level 4011700100026 and each horizontal section of gamma-transition scheme)4011700100027 CORRECTION Graphite was used to measure background due to the 4011700100028 scattering of fast and thermal neutrons by sample. 4011700100029 ~ 30 % of total number of counts was due to background.4011700100030 ADD-RES Gamma transition schemes for Si-31 and S-35. 4011700100031 ERR-ANALYS (ERR-S) All errors are statistical 4011700100032 HISTORY (19720814C) 4011700100033 (19860514U) Some corrections are made 4011700100034 and 'REACTION' keyword introduced 4011700100035 (20141115A) SD: Updated to new date formats,lower case.4011700100036 Corrections according last EXFOR rules and Dict. 4011700100037 Ref. on Engl.transl. of YF added.
