Both samples were encapsulated in 3154000100015 0.1 mm thick Al cans. The samples are cylinders 4 cm in3154000100016 length and 2 cm in diameter for 6Li and 2.5 cm in 3154000100017 diameter for 7Li. An identical empty Al can was also 3154000100018 prepared for sample out background measurements. 3154000100019 DETECTOR (SOLST) The TOF spectrometer 3154000100020 MONITOR (1-H-1(N,EL)1-H-1,,DA) In order to get values of DDX, 3154000100021 polyethylene scatterer of identical size of the sample 3154000100022 was used to measure the total counts for the n-p 3154000100023 scattering peak Nh(25 degr.) at 25 degr. The n-p 3154000100024 scattering neutron counts Nh(25 degr.) were accurately 3154000100025 measured with the statistical uncertainty < 2%. 3154000100026 ERR-ANALYS (DATA-ERR) The error sources of the data mainly come 3154000100027 from; 3154000100028 * the counting statistics (about 10%-20% for most of 3154000100029 energy bins), 3154000100030 * the background subtraction (about 10%), 3154000100031 * the efficiency of neutron detector (about 3%) 3154000100032 * the correction errors of Monte-Carlo calculation, 3154000100033 which were about 3% for 6,7Li samples and 3154000100034 1% for polyethylene. 3154000100035 (EN-ERR-DIG) Digitizing error 3154000100036 (ERR-DIG) Digitizing error 3154000100037 STATUS (CURVE) Data from figures of the article 3154000100038 HISTORY (20050210C) SD 3154000100039 (20070115D) Entry deleted.
