M049200100004 AUTHOR (H.Ries,U.Kneissl,G.Mank,H.Stroher,W.Wilke,R.Bergere, M049200100005 P.Bourgeois,P.Carlos,J.L.Fallou,P.Garganne, M049200100006 A.Veyssiere,L.S.Cardman) M049200100007 REFERENCE (J,PL/B,139,254,1984) M049200100008 INSTITUTE (2FR SAC) M049200100009 FACILITY (LINAC,2FR SAC) M049200100010 INC-SOURCE (QMPH,TAGD) Using the published data the energy M049200100011 resolution may be estimated to be about 1.5%. M049200100012 METHOD (EXTB) M049200100013 DETECTOR (IOCH) A gaseous ionization detector (the parallel M049200100014 plate avalanche detector (PPAD)). M049200100015 SAMPLE The fissile target material was electrolytically M049200100016 deposited on the ppad foils. M049200100017 PART-DET (FF) M049200100018 ANALYSIS Direct measurements of cross section values for M049200100019 coincidence counts between the tagged electrons from M049200100020 linac and the fission detector taking into account M049200100021 such quantities as efficiency of tagging and M049200100022 equivalent thickness of the target. M049200100023 ERR-ANALYS (DATA-ERR) The quoted error bars contain both M049200100024 statistical and systematic uncertainties. M049200100025 COMMENT The absolute photofission cross sections of U-235,238 M049200100026 have been measured in the ehergy range 40 - 105 MeV M049200100027 with tagged photons, using parallel plate avalanche M049200100028 counters for a direct detection of the fission M049200100029 fragments. The measured cross sections are nearly M049200100030 constant in the investigated energy range and amount M049200100031 to about 17 mb for both isotopes.
