Thickness = 0.55524 cm. 1029500100010 METHOD (DIFFR) Pendelloesung fringe patterns within the Bragg 1029500100011 reflection were used to determine the coherent 1029500100012 scattering amplitude. 1029500100013 DETECTOR (BF3) Slow neutron BF3 detector. 1029500100014 Incident beam highly collimated (3 min arc). Exit slit 1029500100015 placed exactly at center of the Bragg reflection band.1029500100016 ANALYSIS Intensity data as a function of crystal orientation 1029500100017 were fitted to the Kato spherical wave theory. 1029500100018 Assumed neutron charge amplitude = 0.00043E-12. 1029500100019 CORRECTION Corrections for use of finite size slit opening and 1029500100020 for crystal curvature were applied. 1029500100021 ERR-ANALYS (DATA-ERR) Standard deviation. 1029500100022 STATUS (APRVD) Approved by author. 1029500100023 HISTORY (19721117C) 1029500100024 (19830117A) Converted to REACTION formalism 1029500100025 (20011227A) Updated to new date formats, lower case. 1029500100026 Added SF4 to reaction string. 1029500100027 ENDBIB 25 0 1029500100028 NOCOMMON 0 0 1029500100029 ENDSUBENT 28 0 1029500199999 SUBENT 10295002 20011227 00001029500200001 BIB 1 1 1029500200002 REACTION (14-SI-0(N,THS)14-SI-0,COH,AMP) 1029500200003 ENDBIB 1 0 1029500200004 NOCOMMON 0 0 1029500200005 DATA 3 1 1029500200006 EN-DUMMY DATA DATA-ERR 1029500200007 EV FERMI FERMI 1029500200008 0.0253 4.1491 0.0010 1029500200009 ENDDATA 3 0 1029500200010 ENDSUBENT 9 0 1029500299999 ENDENTRY 2 0 1029599999999
