Absolute neutron flux 3099100100016 was determined by counting the associated alpha par- 3099100100017 ticles produced in the T(d,n)He-4 reaction. 3099100100018 DETECTOR (GELI) 110.7 cm3 3099100100019 ANALYSIS (SHAPE) Experimental data were analyzed by a peak- 3099100100020 fitting program which is capable of resolving multi- 3099100100021 plets. 3099100100022 CORRECTION Corrections for neutron flux attenuation and gamma 3099100100023 ray self-absorption in the sample were calculated with 3099100100024 Monte Carlo simulation. Also multiple scattering, 3099100100025 absorption of neutrons by target backing and cooling 3099100100026 water and size and anisotropy of the neutron source 3099100100027 were taken into account in the determination of the 3099100100028 cross sections. 3099100100029 ERR-ANALYS (DATA-ERR) Total uncertainty was about 5% for the 3099100100030 main gamma lines, including: 3099100100031 (ERR-1,,2.5) Error of neutron flux determination 3099100100032 was not more than 2.5%. 3099100100033 STATUS (TABLE) Data are taken from Table 1 of Conf. on Nucl. 3099100100034 Data for Sci. and Technol., Juelich 1991, page 332. 3099100100035 HISTORY (19920722C) HW 3099100100036 (19940411D) HW.- Subents 003 and 004 deleted, data move3099100100037 to subent 002.- 3099100100038 (19970421A) HW.- Reaction code corrected in subent 002.3099100100039 (20090912A) SD:Updated to new date formats,lower case. 3099100100040 Cosmetic corrections and small additions 3099100100041 Subent 002 was splited into three Subents.
