TITLE Helium ion-induced fission of 197Au from 41.1 MeV to C247300100003

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. C247300100038
