M0492 1 4 AUTHOR (H.Ries,U.Kneissl,G.Mank,H.Stroher,W.Wilke,R.Bergere, M0492 1 5 P.Bourgeois,P.Carlos,J.L.Fallou,P.Garganne, M0492 1 6 A.Veyssiere,L.S.Cardman) M0492 1 7 REFERENCE (J,PL/B,139,254,1984) M0492 1 8 INSTITUTE (2FR SAC) M0492 1 9 FACILITY (LINAC,2FR SAC) M0492 1 10 INC-SOURCE (QMPH,TAGD) Using the published data the energy M0492 1 11 resolution may be estimated to be about 1.5%. M0492 1 12 METHOD (EXTB) M0492 1 13 DETECTOR (IOCH) A gaseous ionization detector (the parallel M0492 1 14 plate avalanche detector (PPAD)). M0492 1 15 SAMPLE The fissile target material was electrolytically M0492 1 16 deposited on the ppad foils. M0492 1 17 PART-DET (FF) M0492 1 18 ANALYSIS Direct measurements of cross section values for M0492 1 19 coincidence counts between the tagged electrons from M0492 1 20 linac and the fission detector taking into account M0492 1 21 such quantities as efficiency of tagging and M0492 1 22 equivalent thickness of the target. M0492 1 23 ERR-ANALYS (DATA-ERR) The quoted error bars contain both M0492 1 24 statistical and systematic uncertainties. M0492 1 25 COMMENT The absolute photofission cross sections of U-235,238 M0492 1 26 have been measured in the ehergy range 40 - 105 MeV M0492 1 27 with tagged photons, using parallel plate avalanche M0492 1 28 counters for a direct detection of the fission M0492 1 29 fragments. The measured cross sections are nearly M0492 1 30 constant in the investigated energy range and amount M0492 1 31 to about 17 mb for both isotopes.
