M045400100004 AUTHOR (Y.Birenbaum,Z.Berant,A.Wolf,S.Kahane,R.Moreh) M045400100005 REFERENCE (J,PRL,61,810,1988) M045400100006 INSTITUTE (3ISLNEG) M045400100007 FACILITY (REAC,3ISLNEG) IRR-2 reactor.

M045400100013 SAMPLE The target was a thin-walled glass vial, 4.4 cm in M045400100014 diameter and 5 cm high, filled with high-purity M045400100015 heavy water D(2)O, 99.8% D). M045400100016 PART-DET (N) M045400100017 DETECTOR (HE3SP) H3-3 spectrometer. M045400100018 ANALYSIS The photoneutron yields at various angles were M045400100019 normalized for the runnung time and the average M045400100020 photon flux during each run. The total absolute M045400100021 D(g,n) reaction cross section measured previously M045400100022 was used to obtaine absolute differential cross M045400100023 sections. At energies not studied previously an M045400100024 interpolation using a smooth exponential function M045400100025 which reproduced the experimental cross sections to M045400100026 within 0.5% was used. M045400100027 REL-REF (R,,Y.Birenbaum+,J,PR/C,32,1825,1985) Data on M045400100028 absolute value of the cross section for the reaction M045400100029 D(g,n). M045400100030 CORRECTION Correction was introduced to take into account the M045400100031 change of the detector efficiency with energy. M045400100032 ERR-ANALYS (ERR-S) statistical errors only. M045400100033 COMMENT The absolute cross section of the photodisintegration M045400100034 of deuterium was measured at 2754 keV using an M045400100035 absorptive method by passing the photons through M045400100036 2-m long absorbers of (H-2)O and (D-2)O.
