M041900100003 AUTHOR (R.B.TAYLOR,P.TEANSOMPRASONG,I.B.WHITTINGHAM) M041900100004 REFERENCE (J,AUJ,34,125,1981) M041900100005 INSTITUTE (3AULQUC) M041900100006 INC-SOURCE (MPH=(63-EU-152(N,G))) M041900100007 SAMPLE Two targets: thin (0.33 cm) and thick (0.66 cm) M041900100008 were used to check for multiple scattering effects. M041900100009 METHOD (EXTB) M041900100010 DETECTOR (GELI) M041900100011 PART-DET (G) M041900100012 ANALYSIS The absolute cross sections were obtained from M041900100013 relative cross sections by comparing the M041900100014 intensity of the compton scattered peak at 7 M041900100015 degrees from special al target with the M041900100016 corresponding compton cross section obtained from M041900100017 the Klein-Nishina formula multiplied by the M041900100018 incoherent scattering function tabulated by M041900100019 Hubbel et al. M041900100020 REL-REF (R,,J.H.Hubbell+,J,JPC,4,471,1975) incoherent M041900100021 scattering functions. M041900100022 ERR-ANALYS (DATA-ERR1) The statistical errors. M041900100023 (DATA-ERR2) The estimated systematic error in the M041900100024 relative cross sections varied from 3% at small M041900100025 angles to 10% at the larger angles. inclusion of M041900100026 an error associated with the setting of each M041900100027 scattering angle yields an estimated error in M041900100028 absolute cross sections of about 10%. M041900100029 COMMENT differential cross sections for elastic scattering M041900100030 of 344, 444, 779, 964, 1086, 1112, and 1408 keV M041900100031 g-rays by tungsten have been measured for six M041900100032 scattering angles from 7 to 45 degrees.
