ENTRY C2473 20200220 C190C247300000001 SUBENT C2473001 20200220 C190C247300100001 BIB 12 37 C247300100002 TITLE Helium ion-induced fission of 197Au from 41.1 MeV to C247300100003 26.8 MeV C247300100004 AUTHOR (E.F.Neuzil) C247300100005 REFERENCE (J,JIN,27,3,1965) C247300100006 #doi:10.1016/0022-1902(65)80182-8 C247300100007 INSTITUTE (1USAWWS) C247300100008 FACILITY (CYCLO,1USAWAU) The 60 in. cyclotron at the C247300100009 University of Washington. C247300100010 SAMPLE The gold targets were arranged using the ordinary C247300100011 stacked foil technique. These stacked foils consisted C247300100012 of four pure gold foils sandwiched between two pieces C247300100013 of zone refined hyper-pure aluminum foil, which C247300100014 served as a catcher for any recoiling fission C247300100015 fragments escaping from the gold target itself. These C247300100016 gold sandwiches were placed at various positions C247300100017 within a stack. In front of each foil was placed a C247300100018 stainless steel or aluminum degrader. C247300100019 DETECTOR (GEMUC) C247300100020 METHOD (STTA,CHSEP) The various species to be separated were C247300100021 obtained using standard radio-chemical techniques. In C247300100022 each experiment the fission fragments were isolated C247300100023 and counted by the usual beta techniques. C247300100024 ANALYSIS (DECAY) From the disintegration rates obtained at the C247300100025 end of the bombardment, the cross-section for the C247300100026 production of a particular fission product was C247300100027 calculated in the usual manner. C247300100028 CORRECTION The disintegration rate was obtained by correcting C247300100029 the activity for absorption of the sample covering, C247300100030 scattering within the Geiger chamber, self absorption, C247300100031 absorption of air and window of the Geiger chamber, C247300100032 back scattering, dead time, and geometry. C247300100033 COMMENT Compiler's comment: Present day 201Tl(a) decay to C247300100034 197Au value is 1534.0 keV, it was ~0.9 MeV in the C247300100035 past. Consequently, alpha beam energies of 41.1, 34.2, C247300100036 28.8 and 26.8 MeV correspond to compound nucleus C247300100037 excitation energies of 40.2, 33.3, 27.9 and 25.9 MeV.
