ENTRY C2473 20200220 C190C2473 0 1 SUBENT C2473001 20200220 C190C2473 1 1 BIB 12 37 C2473 1 2 TITLE Helium ion-induced fission of 197Au from 41.1 MeV to C2473 1 3 26.8 MeV C2473 1 4 AUTHOR (E.F.Neuzil) C2473 1 5 REFERENCE (J,JIN,27,3,1965) C2473 1 6 #doi:10.1016/0022-1902(65)80182-8 C2473 1 7 INSTITUTE (1USAWWS) C2473 1 8 FACILITY (CYCLO,1USAWAU) The 60 in. cyclotron at the C2473 1 9 University of Washington. C2473 1 10 SAMPLE The gold targets were arranged using the ordinary C2473 1 11 stacked foil technique. These stacked foils consisted C2473 1 12 of four pure gold foils sandwiched between two pieces C2473 1 13 of zone refined hyper-pure aluminum foil, which C2473 1 14 served as a catcher for any recoiling fission C2473 1 15 fragments escaping from the gold target itself. These C2473 1 16 gold sandwiches were placed at various positions C2473 1 17 within a stack. In front of each foil was placed a C2473 1 18 stainless steel or aluminum degrader. C2473 1 19 DETECTOR (GEMUC) C2473 1 20 METHOD (STTA,CHSEP) The various species to be separated were C2473 1 21 obtained using standard radio-chemical techniques. In C2473 1 22 each experiment the fission fragments were isolated C2473 1 23 and counted by the usual beta techniques. C2473 1 24 ANALYSIS (DECAY) From the disintegration rates obtained at the C2473 1 25 end of the bombardment, the cross-section for the C2473 1 26 production of a particular fission product was C2473 1 27 calculated in the usual manner. C2473 1 28 CORRECTION The disintegration rate was obtained by correcting C2473 1 29 the activity for absorption of the sample covering, C2473 1 30 scattering within the Geiger chamber, self absorption, C2473 1 31 absorption of air and window of the Geiger chamber, C2473 1 32 back scattering, dead time, and geometry. C2473 1 33 COMMENT Compiler's comment: Present day 201Tl(a) decay to C2473 1 34 197Au value is 1534.0 keV, it was ~0.9 MeV in the C2473 1 35 past. Consequently, alpha beam energies of 41.1, 34.2, C2473 1 36 28.8 and 26.8 MeV correspond to compound nucleus C2473 1 37 excitation energies of 40.2, 33.3, 27.9 and 25.9 MeV.
