M044300100011 DETECTOR (THRES,NAICR) An Al-27(n,alpha)Na-24 threshold M044300100012 detector has been used to detect fast photoneutrons M044300100013 emitted from various nuclei. The residual Na-24 M044300100014 activity (half-life of 15 hr, Eg = 1.37 and 2.76 M044300100015 MeV) was detected with a carefully shielded M044300100016 scintillation counter. M044300100017 ANALYSIS Direct detection of photoneutrons. M044300100018 ERR-ANALYS (DATA-ERR) No information about source of M044300100019 uncertainties. M044300100020 COMMENT Using an Al-27(n,alpha)Na-24 threshold detector, the M044300100021 angular distributions of fast photoneutrons from six M044300100022 elements (beryllium, carbon, tin, tantalum, lead, M044300100023 and bismuth) have been measured. For 34 MeV M044300100024 bremsstrahlung the angular distributions were found M044300100025 to be asymmetric about a position 90 degrees M044300100026 relative to the direction of the incident M044300100027 bremsstrahlung and were peaking in a forward M044300100028 direction.
