M046000100004 AUTHOR (F.D.Smit,F.D.Brooks) M046000100005 REFERENCE (J,NP/A,465,429,1987) M046000100006 INSTITUTE (3SAFSCT) M046000100007 FACILITY (VDG,3SAFSCT) M046000100008 INC-SOURCE (MPH=(11-NA-23(D,P)11-NA-24)) Radioactive nucleus M046000100009 Na-24. Eg = 2.75 MeV. M046000100010 METHOD (COINC) The photoprotons were detected in crystal and M046000100011 the associated photoneutrons were detected in M046000100012 delayed coincidence in a stilbene crystal at a M046000100013 distance of 170 mm. M046000100014 SAMPLE The deuterated anthracene scintillation crystal was M046000100015 used simultaneously as target and as photoroton M046000100016 detector. M046000100017 PART-DET (N) M046000100018 (P) M046000100019 DETECTOR (SCIN,SCIN) M046000100020 ANALYSIS Photodisintegration runs were made at six laboratory M046000100021 angles Theta-n = 30, 45, 60, 90, 120, and 135 M046000100022 degrees. For each angle the photoneutron yield was M046000100023 determined by integrating the counts in the M046000100024 photoneutron peak and by normalizing to a constant M046000100025 flux of incident 2.75 MeV gamma rays. M046000100026 CORRECTION Corrections were made for background, geometry, dead M046000100027 time losses, and relative detection efficiency of M046000100028 neutron detector. M046000100029 ERR-ANALYS (ERR-S) Statistical errors. M046000100030 COMMENT The angular distribution of neutrons from deuteron M046000100031 photodisintegration by 2.75 MeV gamma rays was M046000100032 measured at six laboratory angles between 30 and 135 M046000100033 degrees. The dipole cross section ratio sig-m/ sig-e M046000100034 = 0.290 (0.021) was derieved from the measurements. M046000100035 The least squares fit to angular distribution of M046000100036 neutrons led to the value a/b = 0.193 (0.014).
