From shape and position analysis of these 3144200100021 the angular distributions of Li-7 recoils and thereby 3144200100022 the angular distributions of the inelastic scattered 3144200100023 neutrons were determined. 3144200100024 (TOF) Time-of-flight techniques were applied in order 3144200100025 to suppress the background from neutrons in the gamma 3144200100026 spectra. 3144200100027 DETECTOR (SCIN,HPGE) A plastic scintillator Ne211 was used as 3144200100028 a monitor of the TOF system. 3144200100029 ANALYSIS Monte Carlo simulations of the gamma-ray spectra 3144200100030 were done which included several corrections. 3144200100031 These simulations, expanded in Legendre polynomials, 3144200100032 were fitted to the experimental data with the Least 3144200100033 Squares Fitting method. 3144200100034 CORRECTION Several corrections were taken into account, i.e. 3144200100035 - The primary neutron energy spread. 3144200100036 - The solid angle correction for the sample to 3144200100037 neutron target. 3144200100038 - The speed reducing effect of recoil Li* before 3144200100039 emitting the gamma-ray. 3144200100040 - Gamma detector resolution. 3144200100041 These corrections were calculated in the Monte- 3144200100042 Carlo simulations mentioned above. 3144200100043 ERR-ANALYS (DATA-ERR) Uncertainty in the fitting of the data. 3144200100044 STATUS (TABLE) Data corresponding to fig. 1 of 3144200100045 C,91JUELIC,,323,1991 is from priv.comm. with author. 3144200100046 HISTORY (19940907C) HW. 3144200100047 (19970815U) HW. -Reference added. 3144200100048 (20100221A) SD:Updated to new date formats, 3144200100049 Cosmetic changes and corrections. 3144200100050 ENDBIB 48 0 3144200100051 NOCOMMON 0 0 3144200100052 ENDSUBENT 51 0 3144200199999 SUBENT 31442002 20100306 31463144200200001 BIB 1 1 3144200200002 REACTION (3-LI-7(N,INL)3-LI-7,PAR,DA,,LEG/RS) 3144200200003 ENDBIB 1 0 3144200200004 COMMON 1 3 3144200200005 E-LVL 3144200200006 MEV 3144200200007 .478 3144200200008 ENDCOMMON 3 0 3144200200009 DATA 4 16 3144200200010 EN NUMBER DATA DATA-ERR 3144200200011 MEV NO-DIM NO-DIM NO-DIM 3144200200012 9.0 1.0 .8724 .0097 3144200200013 9.0 2.0 .9954 .0450 3144200200014 9.0 3.0 .0228 .0124 3144200200015 9.0 4.0 .2651 .1368 3144200200016 9.5 1.0 .9613 .0100 3144200200017 9.5 2.0 1.0153 .0432 3144200200018 9.5 3.0 .4542 .0984 3144200200019 9.5 4.0 .6856 .1197 3144200200020 10.0 1.0 1.0316 .0152 3144200200021 10.0 2.0 1.1501 .0805 3144200200022 10.0 3.0 .6642 .1205 3144200200023 10.0 4.0 .5254 .2176 3144200200024 14.9 1.0 .7655 .0712 3144200200025 14.9 2.0 .2109 .1390 3144200200026 14.9 3.0 .3704 .3216 3144200200027 14.9 4.0 .3342 .2270 3144200200028 ENDDATA 18 0 3144200200029 ENDSUBENT 28 0 3144200299999 ENDENTRY 2 0 3144299999999
