M021400100003 AUTHOR (R.W.Fast,P.A.Flournoy,R.S.Tickle,W.D.Whitehead) M021400100004 INSTITUTE (1USAVIR) M021400100005 REFERENCE (J,PR,118,(2),535,1960) M021400100006 #doi:10.1103/PhysRev.118.535 M021400100007 FACILITY (SYNCH,1USAVIR) M021400100008 INC-SOURCE (BRST) M021400100009 METHOD (EXTB,SITA) M021400100010 DETECTOR (BF3) Halpern-type photoneutron detection system used. M021400100011 PART-DET (N) M021400100012 ANALYSIS (PLA) the method of Penfold and Leiss was used to M021400100013 extract the total neutron cross section from the M021400100014 yield curves. M021400100015 COMMENT The photoneutron yields from Li, N14, and Ar40 have M021400100016 been measured as a function of the maximum M021400100017 bremsstrahlung energy from threshold to M021400100018 approximately 50 MeV. Sigma t = (g,n) + sigma(g,pn) M021400100019 + 2sigma(g,2n) +.... results are compared with M021400100020 previous findings of other laboratories. No gross M021400100021 structure was detected in the lithium cross section M021400100022 in the giant resonance region. The data indicate M021400100023 that lithium has a high-energy tail on the cross M021400100024 section of considerable magnitude. M021400100025 ERR-ANALYS (DATA-ERR) Root-mean-squared errors.
