Filter components: 52Cr, 58Ni,60Ni, 3224000100015 Si, 10B, Al. 3224000100016 METHOD (FNB) 3224000100017 DETECTOR (PROPC) For registration of the scattered neutrons, 3224000100018 five specially designed detectors were used. Every 3224000100019 detector is the assembly of seven helium-3 counters 3224000100020 CNM-17 (18 mm diameter, 220 mm length, 7 at 3224000100021 pressure), which works with one preamplifier. For 3224000100022 every assembly of the counters the units were picked 3224000100023 up with the identical gas amplification, so that no 3224000100024 expansion of helium peak took place in spectrums. 3224000100025 These assemblies have the individual radiation 3224000100026 shielding as the cylinder thin-walled container (100 3224000100027 mm external diameter, 300 mm length) filled with the 3224000100028 boron carbide. 3224000100029 SAMPLE From two to four carbon samples were used for 3224000100030 measurements at each energy. The samples are a set of 3224000100031 carbon disks (from one to four units), each with a 3224000100032 thickness of 1mm and a diameter of 30.4 mm(C 99.997 %).3224000100033 These carbon disks were made by GoodFellow Cambridge 3224000100034 Limited Company (England). 3224000100035 1) Filter 2 keV.

Two samples thick: 0,0088707 and 3224000100040 0.02659927 atom/b. 3224000100041 MONITOR (82-PB-208(N,EL)82-PB-208,,SIG,,AV) The thickness of 3224000100042 the 208Pb sample was 0.00616+-1E-05 nucl/barn, 3224000100043 enrichment of 208Pb to 98.3%, chemical purity 99.98%. 3224000100044 Values for elastic scattering cross section of 208Pb 3224000100045 were taken from JENDL-3.3. 3224000100046 CORRECTION The normalization factor, which is a function of 3224000100047 detector efficiency, thickness of the carbon samples, 3224000100048 thickness of the 208Pb sample, geometry, etc., for each3224000100049 sample and for each filter energy has been obtained 3224000100050 through Monte-Carlo calculation with our codes ROZSI 3224000100051 and ROZSMK. 3224000100052 ERR-ANALYS (DATA-ERR) Total error includes: statistical error of 3224000100053 measurements;errors of dimension and weight of samples.3224000100054 STATUS (TABLE) Data obtained from the author. 3224000100055 HISTORY (20161013) UKRNDC 3224000100056 (20200527A) OG.
