M044400100016 SAMPLE The berillium target. M044400100017 PART-DET (N) M044400100018 DETECTOR (GEMUC) saturated solutions of sodium and potassium M044400100019 permanganate were used as the Szilard-Chalmers M044400100020 neutron detector. The activity of Mn-56(o-2) was M044400100021 measured by geiger counter. M044400100022 ERR-ANALYS (ERR-S) The errors given are statistical. M044400100023 CORRECTION six major corrections were required. These were the M044400100024 corrections for: M044400100025 - the differential absorption of gamma-rays in M044400100026 beryllium and heavy water (used for background M044400100027 measurements); M044400100028 - the slight difference in geometry of the samples M044400100029 (beryllium and heavy water); M044400100030 - the (n,2n) reaction occuring in beryllium, M044400100031 produced by photoneutrons; M044400100032 - the differential escape of neutrons from the M044400100033 detector; M044400100034 - the collisions of neutrons and Be-9, with loss M044400100035 of neutron energy, incide the blocks; M044400100036 - the Be-al alloy used in place of beryllium for M044400100037 one experiment. M044400100038 COMMENT Cross sections for the reaction Be-9(g,n)Be-8 for M044400100039 monochromatic gamma rays in the energy range from M044400100040 2.6 to 8.1 MeV have been obtained using a large M044400100041 Szilard-Chalmers neutron detector.
