The neutron 1034300100009 intensity at the sample was 1.5*10**6 n/cm**2/sec at 1034300100010 a wavelength of 1.07 Angstrom. 1034300100011 SAMPLE Alpha- and beta-DOX crystals. 1034300100012 METHOD (DIFFR) Neutron diffraction 1034300100013 DETECTOR (PROPC) BF3 counter 1034300100014 CORRECTION An absorption correction using an absorption 1034300100015 coefficient of 0.13 cm**-1 computed from the true 1034300100016 absorption cross sections of the atomic species 1034300100017 present was applied to the alpha-DOX data. No 1034300100018 absorption correction was made for beta-DOX. 1034300100019 Extinction treated in the least-squares refinement. 1034300100020 ANALYSIS Because the deuterium percentage in the crystal was not1034300100021 accurately known, the deuterium scattering lengths 1034300100022 were considered parameters in a least squares program.1034300100023 ERR-ANALYS (DATA-ERR) No information on source of uncertainties. 1034300100024 STATUS (APRVD) Approved by author 1034300100025 HISTORY (19731221C) 1034300100026 (19830325A) Converted to REACTION formalism 1034300100027 (20020927A) Updated to new date formats, lower case. 1034300100028 Reaction product added to assumed reactions. 1034300100029 Data corrected to minimum value. 1034300100030 ENDBIB 28 0 1034300100031 NOCOMMON 0 0 1034300100032 ENDSUBENT 31 0 1034300199999 SUBENT 10343002 20020927 00001034300200001 BIB 2 3 1034300200002 REACTION (1-H-2(N,EL)1-H-2,,AMP) 1034300200003 ASSUMED (ASSUM1,6-C-0(N,EL)6-C-0,,AMP) 1034300200004 (ASSUM2,8-O-0(N,EL)8-O-0,,AMP) 1034300200005 ENDBIB 3 0 1034300200006 NOCOMMON 0 0 1034300200007 DATA 5 1 1034300200008 EN-DUMMY DATA-MIN DATA-ERR ASSUM1 ASSUM2 1034300200009 EV FERMI FERMI FERMI FERMI 1034300200010 0.0253 6.51 0.02 6.61 5.57 1034300200011 ENDDATA 3 0 1034300200012 ENDSUBENT 11 0 1034300299999 ENDENTRY 2 0 1034399999999
