The energy of the neutron, in 3038700100014 this arrangement, was approximately 3.7 MeV. 3038700100015 SAMPLE 99% pure terbium oxide powder packed into a thin 3038700100016 ring-shaped polyethylene box, inner diam. of 10.8 cm 3038700100017 and thickness 2 cm. 3038700100018 DETECTOR (GELI) 40 cm3 Ge(Li) detector, with a resolution of 3038700100019 3 keV at E(gamma)=1 MeV. The detector was coupled to 3038700100020 a 4096 channel analyser. 3038700100021 The relative efficiency of the detector was determined 3038700100022 with a Ra-226 and a Sc-46 source. 3038700100023 The energies in the gamma spectrum were determined 3038700100024 with Cs-137,Co-57,Co-60,ra-226,Sc-46,Na-22 and Th-C''. 3038700100025 PART-DET (G) Gammas. 3038700100026 STATUS (APRVD) Approved by Felsteiner, 77/05/18. 3038700100027 HISTORY (19770308C) KO. 3038700100028 (19770607U) KO.- 'Aprvd' added.- 3038700100029 (20090115A) BIB section updated 3038700100030 CORRECTION Self-absorption of the gamma in the sample was 3038700100031 corrected. 3038700100032 ENDBIB 30 0 3038700100033 NOCOMMON 0 0 3038700100034 ENDSUBENT 33 0 3038700199999 SUBENT 30387002 20090105 31343038700200001 BIB 5 11 3038700200002 REACTION (65-TB-159(N,INL)65-TB-159,,SPC,,REL) 3038700200003 MONITOR Relative intensity. 3038700200004 COMMENT Although the existence of 855-keV state was proved by 3038700200005 the presence of its de-excitation gamma-rays of 237 and3038700200006 274 keV, no transition from the 855-keV level to the 3038700200007 ground state was observed in this experiment, 3038700200008 apparently due to the low transition rate and heavy 3038700200009 background in this energy region. 3038700200010 FLAG (1.)
