A pump circulated the 1132100100012 deuterium through a cooling system and returned the 1132100100013 cold gas to the chamber through a jet aimed at the foil1132100100014 SAMPLE Scatterers were cylinders two inches long with 1132100100015 diameters equal to approximately one-half of a mean 1132100100016 free path for 5-MeV neutrons, except oxygen and barium.1132100100017 DETECTOR (SCIN) Biased scintillator. The neutron detector 1132100100018 consisted of twenty layers of plastic scintillator 1132100100019 0.001 inch thick separated by glass disks 0.050 inch 1132100100020 thick and 2 inches in diam., all mounted on an 1132100100021 RCA 6342 photomultiplier. 1132100100022 CORRECTION The cross sections were corrected for the difference 1132100100023 in counter efficiency for the detection of the primary 1132100100024 and scattered neutrons, since momentum transfer to the 1132100100025 target nucleus reduces the energy of the scattered 1132100100026 neutrons.Also corrections were made for the attenuation1132100100027 of the incident flux in the scatterers and for 1132100100028 multiple scattering. 1132100100029 REL-REF (M,,J.Blok+,J,PHY,18,809,1952) -method of the 1132100100030 multiple-scattering corrections calculation 1132100100031 ERR-ANALYS (DATA-ERR) Statistical errors plus an estimation of 1132100100032 the errors in the multiple scattering 1132100100033 STATUS (SCSRS) 1132100100034 (TABLE) data received in private comm., Hill, 1961/8. 1132100100035 HISTORY (19761014T) Translated from SCISRS 1132100100036 (19820324A) converted to reaction formalism 1132100100037 (20110727A) SD:Updated to new date formats,lower case. 1132100100038 corrected according to last EXFOR rules and Dict. 1132100100039 BIB updated.

This cross section was measured with a high 1132100300006 purity sample of sintered Al2O3, and then the 1132100300007 appropriate subtraction of the Al cross section was 1132100300008 made. Since the subtraction of two not too dissimilar 1132100300009 numbers may be subject to considerable error, a more 1132100300010 direct approach was tried. A thin-walled brass can was 1132100300011 constructed in order to measure the scattering from 1132100300012 water. Of all the compounds of oxygen, water has a 1132100300013 decided advantage for elastic-scattering measurement in1132100300014 that the contribution from the scattering from hydrogen1132100300015 is almost negligible for angles larger than about 1132100300016 40. degr. because of the large energy loss of the 1132100300017 scattered neutrons. Background runs were made with the 1132100300018 empty can in place. 1132100300019 ENDBIB 17 0 1132100300020 NOCOMMON 0 0 1132100300021 DATA 3 10 1132100300022 COS DATA DATA-ERR 1132100300023 NO-DIM
