Through Bragg diffraction in NaCl(200) the 3091400100011 monoenergetic 0.0253 eV neutrons were selected. Between3091400100012 the NaCl(200) monochromator and the measured sample a 3091400100013 mechanical monochromator was inserted in order to cut 3091400100014 off the neutrons with high energy. 3091400100015 SAMPLE Gold foils, purity 99.9%, diameter 4.2 cm, thickness 3091400100016 1.527g/cm2. 3091400100017 METHOD (MANGB) 3091400100018 DETECTOR (BF3) Using 80% enriched boron-10. 3091400100019 (D4PI) using manganese sulphate solution as detector 3091400100020 medium. 3091400100021 CORRECTION For the total cross section corrections have been made 3091400100022 for the secondary-neutron effect and dead time of 3091400100023 detecting system. For the absorption cross section 3091400100024 of gold corrections have been made for the reflected- 3091400100025 neutron effect, secondary-neutron effect, escaped- 3091400100026 neutron effect and the boundary effect of the sample. 3091400100027 ERR-ANALYS (DATA-ERR) Errors have been considered for: 3091400100028 * counting statistics, 3091400100029 * energy resolution and 3091400100030 * energy calibration of the crystal spectrometer. 3091400100031 STATUS (TABLE) Data from the text of CST,1965,(10),848,1965 3091400100032 HISTORY (19880522C) DW 3091400100033 (20090912A) SD:Updated to new date formats,lower case. 3091400100034 (20171006A) VS.
